History Main / DoItYourselfThemetune

* The Theatre/{{Tsukiuta}} stage play series, which generally are not musicals, usually have a theme song titled after the play, with a theme song sung by the cast.

* WebVideo/ThreeDBotMaker: ''King of the Mountain'' videos often end with 2D rapping or even singing about the series, sometimes in relation to what just occurred.

* All the music in ''WebAnimation/ReynaldoTheAssassin'' (theme tune and otherwise) is done by director/TalkingToHimself actor Oneclipleft.
* The creator of ''WebVideo/PrettyDudes'', Chance Calloway, also co-wrote and sings on the "Pretty Dudes Anthem" that kicks off each episode.

* ''WebVideo/TheHappyVideoGameNerd'': He covered the AVGN theme himself, playing the guitar and singing modified lyrics. Later, his band Starship Amazing remixed the song, and eventually they composed and performed an original instrumental piece.
* ''WebVideo/KamenRiderExAidTheAbridgedSeries'' has one for Nico Saiba, [[https://www.youtube.com/watch?v=TTpjYffCnhY NICO NICO ★ RIDE FEVER]], a SongParody written and performed by Nico's voice actress.
* The theme song for ''WebVideo/CriticalRole'' and its animated series ''The Legend of Vox Machina'', "Your Turn to Roll", was composed by Creator/SamRiegel, and sung by Riegel, Creator/LauraBailey, Creator/AshleyJohnson, and Creator/TravisWillingham. All four are members of the principal cast.

* Wrestling/KeithLee raps his own NXT theme song "Limitless" and his WWE main roster theme song "Born to Bring It".

* Swerve Strickland does the rapping on his Wrestling/AllEliteWrestling theme "High Pressure".

* The WWE produced an album called ''WWE Originals'' released January 13, 2004 which were songs all sung by the wrestlers or divas on the roster. Some were used briefly as actual themes for the respective wrestlers; briefly because, despite the valiant efforts of [[SugarWiki/AwesomeMusic Jim Johnston]], the world learned that professional wrestlers do not make for great singers (except Wrestling/ChrisJericho, who was already a singer and Lillian Garcia, whose not a wrestler but a ring announcer) Well, despite "Put A Little Ass On It" being laughably terrible, Wrestling/{{Rikishi}} did happen to be a REALLY good singer and John Cena's "Basic Thuganomics did have some longevity"(but that's rapping, not singing)

* Wrestling/MontelVontaviousPorter went out and recorded his second WWE entrance theme without in put from the company. They, accordingly, [[ChorusOnlySong played nothing but the chorus of it]], though Wrestling/NewJapanProWrestling not only played the whole thing but remixed the beat and even added Godzilla's roar to the track. He then used one of his already released themes for his youtube sessions, did another for his New Japan run with [[Wrestling/TheWorldsGreatestTagTeam Shelton Benjamin]] and did a another two themes for his [[Wrestling/ImpactWrestling TNA]] run—one for himself, one for his Beat Down Clan PowerStable.

* Wrestling/KeithLee raps his own NXT theme song "Limitless" and his current main roster theme song "Born to Bring It".

* Wrestling/ScarlettBordeaux, her and Karrion Kross NXT and Main Roster theme song Dead Silent is sung by herself.
* Wrestling/{{Elias}}, his theme song Amen (I'm Going In) is sung and played guitar by himself.
* Hit Row entrance music is rapping by themselves.

* All the music in ''Machinima/ReynaldoTheAssassin'' (theme tune and otherwise) is done by director/TalkingToHimself actor Oneclipleft.

* LetsPlay/ChimneySwift11 sings the intro for the sixth season of the ''Minecraft Files''.

* Wrestling/ChrisJericho's band, Music/{{Fozzy}}, has had their songs as themes for a few of WWE's pay-per-view events, most recently "Martyr No More" for the 2010 Royal Rumble. He never used a Fozzy song as his own theme in WWE, but has used "Judas" in other promotions.

* The WWE produced an album called ''WWE Originals'' released January 13, 2004 which were songs all sung by the wrestlers or divas on the roster. Some were used briefly as actual themes for the respective wrestlers; briefly because, despite the valiant efforts of [[SugarWiki/AwesomeMusic Jim Johnston]], the world learned that professional wrestlers do not make for great singers (except Wrestling/ChrisJericho, who [[already was a singer Music/Fozzy]] and Lillian Garcia, whose not a wrestler but a ring announcer) Well, despite "Put A Little Ass On It" being laughably terrible, Wrestling/{{Rikishi}} did happen to be a REALLY good singer and John Cena's "Basic Thuganomics did have some longevity"(but that's rapping, not singing)

* Wrestling/ScarlettBordeaux, her and Karrion Kross NXT theme song Dead Silent is sung by herself.

* In ''WesternAnimation/IceAgeContinentalDrift'', Keke Palmer's song "We Are" is played over the credits, with the main cast singing along (Keke Palmer voices Peaches, by the way).
* ''WesternAnimation/{{Home}}'' approaches a Do It Yourself ''album'' with its soundtrack. Music/{{Rihanna}}, who voices Tip in the film, also worked with director Tim Johnson to create a concept album for the film. Three of the eight songs there are by her, and one is by co-star Music/JenniferLopez. Which in a way means that some of the songs are tied more to Tip, and that one is tied to Lucy (as they're voiced by Rihanna and Jennifer, respectively).

[[folder:Anime]]
Because the networks and studios notice that pop music and youth-centered stories are "in", this happens a lot in anime to the point where some companies won't hire voice actors unless they can sing as well.

* Since IdolGenre series focuses on a cast of {{Idol Singer}}s, it's naturally a given that the voice actors will be performing the theme tune.
* Every story arc of {{LightNovel/Bakemonogatari}} (usually about two-three consecutive episodes) is focused on a separate character, and comes with an unique opening, sung by that character's [[AlwaysFemale voice actress]].
* "Ready to", the opening of ''Anime/BNABrandNewAnimal'', is sung by Michiru's voice actress in-character.
* ''Franchise/LyricalNanoha'' has a tradition of having the opening theme sung by Fate's voice actor (Creator/NanaMizuki), and the ending theme by Nanoha's (Creator/YukariTamura). This tradition was broken in ''Anime/VividStrike'' (and wouldn't have applied if it did since Nanoha and Fate were both PutOnABus), which had it's opening and ending theme sung by the voice actor's of the new main characters Rinne (Creator/YuiOgura) and Fuka (Creator/InoriMinase).
* Creator/NanaMizuki does this a lot, with examples including ''Anime/BloodC'' (endings), ''Anime/DogDays'' (openings), ''Manga/RosarioPlusVampire'' and ''Anime/{{Symphogear}}'' (openings), to name a few.
* The ''Anime/DogDays'' endings are sung by Creator/YuiHorie, and the ''Anime/{{Symphogear}}'' endings are sung by Creator/AyahiTakagaki. In the latter series, if something else is played instead of the usual ending theme, it's an ImageSong of a character.
** Horie has sung the theme songs for other anime in which she has starred, including ''LightNovel/{{Toradora}}'' and ''Anime/GoldenTime''.
* ''Manga/NegimaMagisterNegiMagi'': The original, the AlternateContinuity and the LiveActionAdaptation have the thirty-one girls of Negi's class singing the theme song. The first two switch what groups of girls are singing every so often, saving the whole class for the final episode, but the third uses the whole class to begin with. This doesn't stop them from including a version sung by the lead set of TrueCompanions -- Asuna, Konoka and Setsuna. Only on the EndingTheme single, though.
* Roughly 83% of any anime that feature Music/MegumiHayashibara.
* ''Anime/CodeGeass'' deserves a special mention here, though, because for one episode [[spoiler:after killing his father]], the EndingTheme is a DarkReprise sung by the voice actor of Lelouch, instead of a separate and seemingly disconnected group. Not even the last episode either; one episode later, the normal ending for this half is back as if nothing ever happened.
* Repeatedly by Creator/AyaHirano, best known as the voices of Haruhi and Konata from ''[[LightNovel/HaruhiSuzumiya The Melancholy of Haruhi Suzumiya]]'' and ''Anime/LuckyStar'', respectively. She performed both the OP and ED for Haruhi (and ''as'' Haruhi), and along with the other members of the main cast, did the OP to Lucky Star too.
** Also played with within the universe itself with Mikuru being made to sing the theme song for the StylisticSuck SOS brigade movie, "The Adventures of Mikuru Asahina."
** For the "Second Coming" of ''Haruhi'' although, she sings the new ending "Tomare" as Haruhi, but she sings the new intro "Super Driver" in her own voice.
* Creator/RicaMatsumoto has done several opening themes for ''Anime/{{Pokemon}}'', where she does the voice of Satoshi (Ash). This includes three songs for the original series, two for ''Advanced Generation'', a duet with Creator/MegumiToyoguchi (Dawn's seiyuu) for ''Diamond & Pearl'', two of three ''Best Wishes!'' openings, the last opening for ''XY&Z'', and the first opening for ''Sun and Moon''.
** This is a trend started almost immediately with the show, as she is the singer for the first opening theme.
** And several ending themes for ''Anime/{{Pokemon}}'' are sung by members of the cast. Seiyuus for Ash, Misty, Brock, May, Professor Oak, Team Rocket and Bonnie have at least contributed one ending to the long-running series.
** Not to mention Rica both playing Bikky in the ''Manga/{{FAKE}}'' OAV as well as singing the ending theme "Starlight Heaven."
* The ending theme of ''Anime/GatchamanCrowds'' is sung by Maaya Uchida, who voices the protagonist Hajime.
* The ''Manga/SayonaraZetsubouSensei'' theme song are sung by "Zetsubou Shoujo-tachi" - a group made up of the lead female voice actors of the show, often with each singing one line solo.
* The ending song of ''VisualNovel/{{Polyphonica}} Crimson S'' is sung by Haruka Tomatsu, the voice actress for Corti.
* Majority of the songs in ''Anime/FullMoon'' are sung by Music/{{Myco}} of Changin' My Life, especially the ending themes.
* The second[[note]](third if you want to get technical as the singers of the first changed in the third season)[[/note]] ending of ''Anime/SailorMoon'' deserves special mention. Its lyrics were written by the mangaka. The second version, however, subverts this, as it is sung by the actresses of the Inner Senshi, but not their voice actresses in the show; their actresses in the stage musicals.
** In a couple dubs (including the Dutch and the Swedish), Sailor Moon's voice actress even sang the intro theme.
** The third ending theme is performed by the five voice actresses of the inner senshi.
* The voice actors for the Keroro Platoon from ''Manga/SgtFrog'' have done a number of the show's opening and closing themes, including a version of the first opening as performed by the Keroro Platoon.
* Creator/VicMignogna, VA of the main character Dark, sang an English cover of ''Manga/DNAngel's'' theme song.
** Subverted with the ending theme of ''Manga/OuranHighSchoolHostClub''. While he wrote the English translation, he wasn't allowed to sing it because his character, Tamaki, doesn't sing. There is still a version of him singing it [[https://www.youtube.com/watch?v=jbuuaC1yWQA here]].
* Sean Schemmel, the voice of Goku, sung the opening theme in the first ''Anime/DragonBallZKai'' DVD.
** Every DVD released since has used a different member of the cast.
* The OP and ED themes of ''Anime/WeissKreuz'' are sang by [[Creator/TakehitoKoyasu the]] [[Creator/ShinichiroMiki four]] [[Creator/TomokazuSeki leads']] [[Creator/HiroYuki seiyuus.]]
* ''Anime/{{Dancougar}}'' has a version of its ending Burning Love sung by the Juusenki Tai. Fairly awesome.
* The opening themes for the ''Manga/HidamariSketch'' anime are sung by the main four (later six) characters' (Yuno, Miyako, Sae and Hiro, later Nori and Nazuna) voice actresses.
* In ''LightNovel/IsThisAZombie'', Creator/IoriNomizu (Haruna) sings the opening theme for both seasons, while Rie Yamaguchi (Taeko Hiramatsu, a girl from Ayumu's class who frequently talks with him) sings the ending themes for both seasons.
* ''Anime/{{Macross}}'' has plenty of examples, since several of its characters are professional singers:
** ''Anime/MacrossFrontier'''s 2nd OP, "Lion", sung by Creator/MegumiNakajima (Ranka Lee) and [[Music/MayNakabayashi May'n]] (Sheryl Nome).
*** The first OP, "Trianguler", was sung by Creator/MaayaSakamoto who voiced [[spoiler:Ranka's Mother Ranshe]].
** And before that, the opening and ending songs of ''Anime/Macross7'' were not just sung by singing voices of the characters (Yoshiki Fukuyama as Basara Nekki and Chie Kajiura as Mylene Jenius), but are songs by the characters in-universe, as they are included on Fire Bomber albums.
** The opening and 2nd ending themes of ''Anime/MacrossDelta'' are performed by all the members of in-universe GirlGroup Walkure, while the 1st ending is sung by Freyja Wion's actress, Minori Suzuki, and the 2nd ending is sung by Mikumo Guynemer's singing voice, JUNNA. In fact, both the opening and closing themes are sung by the cast during the events of the actual show.
* The voice actors of four main characters of ''Manga/DevilsAndRealist'' are the ones who sing both opening and ending of anime, Believe My Dice and A Shadow's Love Song respectively.
* Creator/AiMaeda performed all but one of the eight ending themes for ''Anime/DigimonAdventure'' through ''Anime/DigimonFrontier'', as well the ending themes to some of the films; she portrayed Mimi Tachikawa in ''Adventure'' and ''Anime/DigimonAdventure02'', but didn't have any roles in ''Anime/DigimonTamers'' or ''Frontier''.
* ''Ro-Kyu-Bu!'' is sung by the five main characters who so happen to have actually formed a group by the same name.
* In the anime version of ''Anime/TheIdolMaster'', Juri Takita (as her character Kotori Otonashi[[note]]Who is not one of the idols. She's an employee for their talent agency 765 Productions, although the anime suggests she had been an idol at one point.[[/note]]) sings one of the ending themes.
** The song Yakusoku also fits, as the ending of episode 20, since, even though the girls are {{Idol Singer}}s they are ''not'' song writers.
** Really, the entire show counts for this, because the characters in-universe sing the songs that are used for all the episodes' openings, endings, and insert songs.[[note]]Most, if not all of which were taken from the games.[[/note]]
* Creator/MaayaSakamoto did this for her debut in ''Anime/TheVisionOfEscaflowne''.
** And has been doing so in about half of the anime where she has a character since.
* Music/MegumiHayashibara does most if not all the opening and ending themes for ''LightNovel/{{Slayers}}'', either solo or with another singer.
** She also does the opening for ''LightNovel/{{Slayers}}''' sister franchise Anime/LostUniverse
** The ending theme to the final episode of the third season, "Somewhere in the World," is sung by Creator/HoukoKuwashima, Filia's voice actress.
* ''LightNovel/InfiniteStratos'' has the ending theme sung by the female main characters, with various versions as more characters are introduced. Check the EvolvingCredits page for details.
* In a possible inversion of this trope, T.M.Revolution, who did the first opening themes for ''Anime/MobileSuitGundamSEED'' and ''Anime/MobileSuitGundamSEEDDestiny'', was given a small role in the first series and a slightly larger and more plot significant role in the second. The singer for one of the ending themes was offered a similar opportunity but turned it down which is why Shiho Hahenfluss never has any lines in the anime.
* ''Anime/OkusamaWaMahouShoujo'' ending is sung by Creator/KikukoInoue, who's the voice for the slightly-older-than-standard MagicalGirl Ureshiko.
* Most people do not know that the theme song to ''Happy Kappy'' is actually preformed by Suguri and Kappy themeselves!
* In ''Anime/PuellaMagiMadokaMagica'', the two ending themes "See You Tomorrow" and "And I'm Home" are sung by Madoka's voice actress and Sayaka's and Kyoko's voice actresses, respectively. This applies only on the DVD; in the anime's original TV airings, the episodes either ran the credits over their final scenes or just used the standard credits.
* Creator/HalkoMomoi performs both the voice acting for Mii and the opening theme in ''Popotan''.
* ''Manga/{{Wagnaria}}'' is interesting in the sense that not only the female leads[[note]]Creator/KanaAsumi, Creator/SakiFujita, Creator/EriKitamura[[/note]] get to sing a theme song (the opening), but the male leads[[note]]Creator/JunFukuyama, Creator/DaisukeOno, Creator/HiroshiKamiya[[/note]] too (the ending). This format is repeated in its second and third seasons as well.
* ''Manga/NoMatterHowILookAtItItsYouGuysFaultImNotPopular'': The ending theme used for most episodes is "No Matter How I Look At It, It's Not My Fault" performed by the actress doing the voice of Tomoko.
* The anime of ''LightNovel/SundayWithoutGod'' has the opening performed by Dee's voice actress, Creator/EriKitamura, while the ending theme is done by Creator/MikakoKomatsu, Ulla's voice actress.
* Creator/HarukaTomatsu, Erii Yamazaki, and [[Creator/MaoIchimichi M.A.O.]] sing "Dating Time", the ending theme for ''Anime/SamuraiFlamenco''.
* ''Manga/SakuraTrick'' has very nearly the entire cast sing the opening theme, and the two leads sing the ending theme.
* ''Manga/MyNeighborSeki'' has an unusual take on this- one of the characters is actually seen [[BreakingTheFourthWall ''making'' the opening]] (drawing, animating, recording), which is entirely in character for him. Fittingly, the opening theme is sung by the voice actress of the girl he is recording, and the lyrics are largely in the vein of "What weird game are you playing today? It's very distracting. Stop it."
* In ''Manga/ACertainScientificRailgun'', Creator/YoshinoNanjo (who plays Maaya Awatsuki) is the vocalist of fripSide, who sings all of the shows opening themes like "only my railgun", "[=LEVEL5=]-judgelight-", "future gazer", "sister's noise", "eternal reality", and "final phase". Creator/YukaIguchi (who plays Index) sings the ending themes "Grow Slowly" and "Stand Still" for ''Railgun S'' (the second season of ''Railgun''), before doing the ending themes "Kakumei Zen'ya" and "Owaranai Uta" for the third season of ''LightNovel/ACertainMagicalIndex''.
* All themes of ''Manga/MinamiKe'' are sung by the {{Seiyuu}}s of the Minami sisters: Creator/RinaSato, Creator/MarinaInoue and Creator/MinoriChihara.
* Most, if not all of the ending songs from ''Manga/TheWorldGodOnlyKnows'' fall under this trope:
** The ending song of the first season's final episode, ''[[https://www.youtube.com/watch?v=9saxcHj6im8 The Dream Traveler of the Integrated Circuit]]'', doubles as StylisticSuck since it's primarily sung off-key by an exhausted [[Creator/HiroShimono Keima.]]
** There's also the opening for the ''Goddesses Arc'', ''[[https://www.youtube.com/watch?v=rNC-i5-Z6LU God Only Knows -Secrets of the Goddess-]]'', featuring [[Creator/SaoriHayami Haqua]] on vocals.
** Coupled with EvolvingCredits, the ending theme ''Kizuna no Yukue'' is sung by the girl who is revealed to be having one of the Goddess (except for [[spoiler:Tenri]] which is already revealed on the ''[[spoiler:Tenri-hen OVA]]'') in that episode (except for Episodes 1, 7 and 8 which have no ending themes and Episode 9 which has a different ending theme altogether).
*** Episode 2: [[spoiler:[[Creator/NaoTouyama Kanon Nakagawa]].]]
*** Episode 3: [[spoiler:[[Creator/KaoriNazuka Tenri Ayukawa]].]]
*** Episode 4: [[spoiler:[[Creator/YukaIguchi Tsukiyo Kujou]].]]
*** Episode 5: [[spoiler:[[Creator/AyahiTakagaki Yui Goido]].]]
*** Episode 6: [[spoiler:[[Creator/KanaHanazawa Shiori Shiomiya]].]]
*** Episode 9: [[spoiler:[[Creator/AyanaTaketatsu Ayumi Takahara]].]]
*** Episode 11: All of the girls above.
** Then, doubling as LyricalDissonance, there's ''[[https://www.youtube.com/watch?v=3alvOcc4LKw The Memory of My First Love]]'',primarily sung by [[Creator/KanaAsumi Chihiro]] as lead vocalist of the ''2B Pencils'' (First as ending theme for the ''4 People and an Idol'' OVA, then accompanied by [[Creator/NaoTouyama Kanon]] on backing vocals in the ''Goddesses Arc'' final episode).
* The endings ''Manga/ICantUnderstandWhatMyHusbandIsSaying'' are sung by Creator/YukariTamura and Creator/KenichiSuzumura, who voice the main characters.
* The opening of ''Manga/GugureKokkurisan'' is sung by Creator/DaisukeOno who voices Kokkuri, and he, Creator/TakahiroSakurai (Inugami) and Creator/JojiNakata (Shigaraki) can be heard conversing in it.
* ''Manga/TheWorldIsStillBeautiful'''s ending theme is sung by the protagonist Nike's voice actress, Rena Maeda.
* The regular opening and ending themes of ''Anime/TheIdolmasterCinderellaGirls'' are sung by all fourteen members of the main cast.
* ''Anime/RollingGirls''' opening theme has the four main girls sing the song (and they're even shown performing it on stage), which is actually [[CoverVersion a cover]] of "Hito ni Yasashiku" by Japanese punk rock band The Blue Hearts.
* ''Literature/FromTheNewWorld'' had two themes altogether, both endings. The first was sung by the main character's, Saki's, VA (Rise Taneda) and the second was sung by another member of the main cast, Kana Hanazawa, Marie's VA.
* Both the [[https://www.youtube.com/watch?v=72LDDi2UvwE opening]] and ending themes of ''Manga/SeiyusLife'' are sung by the main characters voice actresses. They also exist in-universe as the opening and ending themes of their radio show.
** On a bizarrely meta note, the IdolSinger group Aice⁵ (of which the manga's author, Creator/MasumiAsano, is a member) [[https://www.youtube.com/watch?v=IMM-mrlZeaY did a cover of the ending theme]].
* In ''Manga/{{Hanayamata}}'', the actresses for the five main girls perform the opening theme, and they also do their version of the ending theme for the final episode.
* In ''Literature/{{Gate}}'', the ending themes are sung by Creator/HisakoKanemoto (Tuka), Creator/NaoTouyama (Lelei), and Creator/RisaTaneda (Rory).
* ''Manga/KishinDoujiZenki''[='s=] second and third ending themes, "Sleepless Angels" and "Kiseki no Chou Kishin," were both sung by Creator/ChisaYokoyama (Chiaki), with her castmate Creator/MegumiOgata also contributing to the latter.
* The English ending theme to ''Anime/YokaiWatch'' is done by Katie and Jibanyan's voice actress. While Katie is an important character she's Nate's unrequited love instead of the protagonist (though she is the female protagonist in [[VideoGame/YokaiWatch the games]]), and Jibanyan is the series' mascot.
* The opening and ending themes of ''Manga/PrisonSchool'' are done by the voice actors of the FiveManBand protagonists.
* All opening themes for ''Manga/AssassinationClassroom'' are sung by Creator/MaiFuchigami (Nagisa), Creator/NobuhikoOkamoto (Karma), Creator/AyaSuzaki (Kayano), Creator/RyotaOhsaka (Isogai), and Creator/ShintaroAsanuma (Maehara), under the name "3-nen E-gumi Utatan" (Class 3-E Song Unit).
** In Season 1 Episodes 7 and 8, Isogai and Maehara's [=VAs=] are temporarily replaced by Yoshitaka Yamaya (Sugino), Creator/SayuriYahagi (Okuda), and Creator/SatomiSato (Kanzaki), to mirror the events of the Kyoto field trip.
* ''Manga/KurokosBasketball'': Tatsuya Himuro's seiyuu Creator/KisshoTaniyama (with his band GRANRODEO) sings six of the seven openings, even though Himuro is not one of the main characters and he is introduced in season 2. Tetsuya Kuroko's seiyuu Creator/KenshoOno sings the fourth ending and the sixth opening. Kazunari Takao's seiyuu Creator/TatsuhisaSuzuki (with his band OLDCODEX) does three of the seven endings.
* The voice of Princess Silver sings the theme song to ''Anime/YumeNoCrayonOukoku''.
* The ending themes of both seasons of ''LightNovel/KonoSuba'' are sung by the [=VAs=] of Aqua, Megumin, and Darkness (Creator/SoraAmamiya, Creator/RieTakahashi and Creator/AiKayano, respectively).
* In ''Anime/Persona4TheAnimation'', the opening theme of episode 9, which introduces [[IdolSinger Rise]], is the song "True Story" performed by her seiyuu Creator/RieKugimiya. This song would later appear again in Persona 4 Golden, the UpdatedRerelease of the original ''VideoGame/Persona4'', with an English version provided by Creator/LauraBailey.
* ''Manga/MonsterMusume'' has the main girls singing the opening, while the ending is sung by the members of the [=MON=] squad.
* The majority of the songs in the ''[[Anime/NGKnightLamune40 Lamune & 40]]'' series are sung by the voice actors (including the drama CD's):
** In the original TV series, ''NG Knight Lamune & 40'' both [[https://www.youtube.com/watch?v=AAUckZYShpI opening]] [[https://www.youtube.com/watch?v=GJgpTpnvgxA themes]] are sung by Creator/TakeshiKusao in-character as Lamune, and for the endings, the [[https://www.youtube.com/watch?v=Vccpq80gwTM 1st ending]] is sung by Creator/ChisaYokoyama in-character as Milk and the [[https://www.youtube.com/watch?v=yCNEcv8M8NU 2nd ending]] is sung by Chisa, Creator/NaokoMatsui and Creator/SakikoTamagawa in-character as Milk, Lesqua & Cocoa respectively.
** The ''EX'' and ''DX'' OVA's continued this, [[https://www.youtube.com/watch?v=hG0vYmnS8I0 ''EX'''s opening]] is sung Takeshi Kusao with Chisa Yokoyama, Naoko Matsui & Sakiko Tamagawa doing back-up, and [[https://www.youtube.com/watch?v=9LAYsdxSdEI the ending theme]] is sung by Yokoyama, Matsui & Tamagawa, for ''DX'' [[https://www.youtube.com/watch?v=dzA0nBzfuOY the opening]] is a duet between Takeshi Kusao & Creator/KazukiYao, and [[https://www.youtube.com/watch?v=tprjDhVXR6w the first ending]] of ''DX'' is sung by Creator/MegumiHayashibara & Creator/KotonoMitsuishi in-character as the OVA's antagonists, Gold & Silver Mountain Dew respectively.

* The theme song to the anime adaptation of ''Manga/CellsAtWork'' is done by the Japanese and English voice actors for Red Blood Cell (Creator/KanaHanazawa[=/=]Creator/CheramiLeigh), White Blood Cell (Creator/TomoakiMaeno[=/=]Creator/BillyKametz), Killer T Cell (Creator/DaisukeOno[=/=]Creator/RobbieDaymond), and Macrophage (Creator/KikukoInoue[=/=]Creator/LauraPost).

* Manga/SaintSeiyaSaintiaSho opening theme song sung by Aina Suzuki (Shoko), Creator/InoriMinase (Saori/Athena), Creator/MaoIchimichi (Kyoko) and Creator/MegumiNakajima (Mii) and ending theme song sung by Aina Suzuki and Creator/MaoIchimichi.
* Both the opening and ending of ''Manga/{{Rekan}}'' are sung by Amami and Inoue's seiyuus, ''Kido Ibuki'' and ''Yamazaki Erii''.
* Manga/AhoGirl ending song sung by Creator/SumireUesaka (Fuuki Iinchou).
* The opening of ''Anime/IsekaiQuartet'', aptly named [[TitleDrop Isekai Quartet]] and the ending, Isekai Girls Talk, are performed by [=VAs=] of the characters from the four novels that are crossing over. Specifically, the OP is sung by Creator/SatoshiHino (Ainz, from ''LightNovel/Overlord2012''), Creator/JunFukushima (Kazuma, from ''LightNovel/KonoSuba''), Creator/YuusukeKobayashi (Subaru, from ''LightNovel/ReZero'') and Creator/AoiYuuki (Tanya, from ''LightNovel/SagaOfTanyaTheEvil''), and the ED is sung by Aoi Yuuki (Tanya again), Creator/RieTakahashi (Emilia, from ''Re:Zero''), Creator/SoraAmamiya (Aqua, from ''Konosuba'') and Creator/YumiHara (Albedo, from ''Overlord'')
** The second season uses the same characters for the OP, but has [[Creator/SumireUesaka Shalltear]], [[Creator/RieTakahashi Megumin]], [[Creator/InoriMinase Rem]] and [[Creator/SaoriHayami Visha]] singing the ending instead.
* ''Manga/KaguyaSamaLoveIsWar'':
** The DancingTheme for episode 3 of season 1 was sung in-character by Konomi Kohara (Fujiwara's voice actress).
** Season 2's ending theme is sung by Haruka Fukuhara (Tsubame's voice actress).
* Being a show about an idol group, it's no surprise that ''Anime/ZombielandSaga'''s opening and closing themes are sung by said idol group. (With the exception of Creator/KotonoMitsuishi, due to her voicing a nonverbal zombie.)
* ''Anime/PrettyCure'':
** The ending themes of ''Anime/MahoGirlsPrecure'' and ''Anime/HugttoPrettyCure'' are sung by the voice actresses of the Cures themselves.
** The second opening to ''Anime/TropicalRougePrettyCure'' has the Tropical Club (the main cast of the show) singing some parts.
* ''LightNovel/DoYouLoveYourMomAndHerTwoHitMultiTargetAttacks'': The ending theme is sung by Mamako's actress Creator/AiKayano.
* ''Manga/HowHeavyAreTheDumbbellsYouLift'': The opening theme is sung by Hibiki voice actress Creator/FairouzAi and Machio voice actor Creator/KaitoIshikawa. The ending theme is sung by Ishikawa.
* ''LightNovel/CopCraft'': Mayu Yoshioka (Tirana Exedirika) sings the ED "Connected".
* ''Manga/TheKawaiComplexGuideToManorsAndHostelBehavior'': The ending song sungs by Creator/KanaHanazawa (Ritsu), Creator/RinaSato (Mayumi) and Creator/HisakoKanemoto (Sayaka).
* ''Manga/TriageX'': Saeko Zogo (Siren) sings the OP "Triage".
* ''Anime/BurnUp'''s ending theme is sung by Yumiko Shibata, Creator/MikiIto and Creator/KumikoNishihara, who all voice Maki, Reimi and Yuka respectively
** ''Burn Up Excess'''s opening is sung by Mami Kingetsu [[note]] mistranslated as Mami Kanezuki on ADV's DVD's [[/note]], who voices Maki
** ''Burn Up Scramble'''s ending is sung by Creator/MegumiToyoguchi, Creator/RieKugimiya and Creator/MamikoNoto who voice Rio, Maya and Lilika respectively
* It's a tradition for ''Anime/HellGirl'''s end themes to be solo performances by Enma Ai's voice actress, Creator/MamikoNoto, while the opening themes are by full bands. Similarly, the openings show the whole cast and the endings show only Ai (except in Season 3, where deuteragonist Yuzuki makes cameos in silhouette).
* ''Manga/AsteroidInLove'''s opening theme, ''Aruite Ikou!'', is sang by Creator/NaoTouyama (Mikage).
* ''Manga/DontToyWithMeMissNagatoro'': The opening song "Easy Love" is sung by Nagatoro's voice actress, Creator/SumireUesaka.
** The ending song "Colorful Canvas" is sung by [[Creator/SumireUesaka Nagatoro]] and her friends [[Creator/MikakoKomatsu Gamo-chan]], [[Creator/AinaSuzuki Yoshi]] and [[Creator/ShioriIzawa Sakura]].
* ''LightNovel/SkyWizardsAcademy'': The opening "D.O.B" is sung by Rico Flamel's voice actress Creator/IoriNomizu.
* ''Manga/ScienceFellInLoveSoITriedToProveIt'': The show's opening, "Paradox," is sung by Himuro's voice actress Creator/SoraAmamiya.
* ''Manga/WhyTheHellAreYouHereTeacher'': Combines this with a CouchGag by having the seiyu of the teacher in focus for that episode sing the ending credits. The opening credits are also sung by Creator/SumireUesaka, but that doesn't change.
* ''Anime/YuriOnIce'': The ending song, "You Only Live Once" is performed by Creator/WataruHatano, the voice of Georgi Popovich.
* ''Manga/LifeLessonsWithUramichiOniisan'': The opening song "ABC Taiso" is performed by (Iketeru Onii-san) Creator/MamoruMiyano and (Utano One-san) Creator/NanaMizuki. The ending song "Dream on" is performed by Creator/MamoruMiyano.
* The ending theme for ''Anime/{{Betterman}}'', "Chin Requiem", is sung by the show's director, Yoshitomo Yonetani, under the name Mai.

[[folder:Films -- Live-Action]]
* Creator/TomHanks and Creator/DanAykroyd performed a ThemeTuneRap "City of Crime" for the 1987 TheFilmOfTheSeries of ''Franchise/{{Dragnet}}''. They also did a music video, which [[https://www.youtube.com/watch?v=pT_QRKfv8H4 must be seen to be believed]]. It's really HilariousInHindsight considering the saga of Chet Haze, Hanks' white rapper son.
* Creator/JohnCarradine, who played a brief role in ''Film/RedZoneCuba'', also sang the theme tune. His singing voice makes it absolutely clear that he should have perhaps cut back on the smoking.
* Also, his son David Carradine wrote and performed the theme tune to the film ''Sonny Boy''.
* Lead actress Creator/EmilyBrowning sings many of the songs used for the ''Film/SuckerPunch'' soundtrack, including the cover of "Sweet Dreams (Are Made of This)".
* Creator/RobertRodriguez composes the music for the films he directs, as well as editing them, hence his unusual replacement for the "Film By" credit: "Shot, Chopped, and Scored by Robert Rodriguez".
* Creator/JohnCarpenter composes the scores for many of his films (and also, as part of the Coupe de Villes, sang the end title song to ''Film/BigTroubleInLittleChina'').
* Anita Mui was not only a famous actress in Hong Kong, but also a pop star in the early 1980s. Because of this, she ended up performing the theme for ''Film/HeroicTrio''.
* Besides starring in, writing, directing and producing his movies, Creator/CharlieChaplin wrote their music.
* Director Mike Figgis often composes his own scores for his films.
* Creator/BryanSinger regular John Ottman not only directed ''Film/UrbanLegendsFinalCut'', but also did the composing and editing (by trade, he is in fact a composer but also edits Singer's films).
* Creator/SylvesterStallone sang the theme song ("Too Close to Paradise") for his quickly forgotten ''Rocky'' follow-up ''Paradise Alley'', the only movie ever to feature songs performed by Sly, Frank Stallone and ''Music/TomWaits''!
* Creator/ClintEastwood :
** This doesn't quite count since it wasn't actually included in the movie, but Eastwood recorded and released a version of [[https://www.youtube.com/watch?v=4ui-7Rjc-N8 "Burning Bridges"]] from ''Kelly's Heroes''.
** Eastwood subsequently wrote themes for his films as a director (such as ''Film/{{Unforgiven}}'') and then graduated to scoring them -- apparently the likes of Music/LaloSchifrin, Music/JohnWilliams, Jerry Fielding and Music/MauriceJarre were just a warmup. He has written (and at times, sung) [[http://www.imdb.com/name/nm0000142/#soundtrack songs]] or [[http://www.imdb.com/name/nm0000142/#composer full-on scores]] for his movies.
* The title theme of ''Film/{{Spider Baby|OrTheMaddestStoryEverTold}}'' is sung (well, [[LargeHam hammily]] recited) by its star, Lon Chaney Jr.
* Though it isn't listed in the credits, "Lullaby" from ''Film/RosemarysBaby'' (the music that plays over the opening credits) is sung by Mia Farrow herself.
* Clint Mansell's score for ''Abandon'' features vocals from the film's star Creator/KatieHolmes.
* Similarly, Sara Paxton's voice is worked into David Hirschfelder's score for ''Film/{{Aquamarine}}'' (Paxton and Creator/EmmaRoberts also have songs on the soundtrack).
* The Wrestling/HulkHogan film ''Mr. Nanny'' has a theme tune by musical artist Buster Poindexter, who plays the villain in the film. The song, however is called "Rough Stuff", since that was the WorkingTitle of the movie.
* Crispin Glover sings Music/MichaelJackson's "Ben" over the end credits in the 2003 version of ''Literature/{{Willard}}''. He's actually really good.
* The opening and ending themes from ''Film/MadMaxBeyondThunderdome'' were both sung by Tina Turner, who played the BigBad Aunty Entity.
* For the original film version of Film/{{MASH}}, director Creator/RobertAltman needed a deliberately stupid, overly emotional song to be sung at the funeral of a character. He got the music from Johnny Mandel, and he ''wanted'' to write the words himself, but found he couldn't write something "stupid enough." So he passed the job to his 14-year-old son, Mike Altman. The result, "Suicide Is Painless", went on [[SpringtimeForHitler to reach #1 on the UK music charts.]] It became the theme for [[Series/{{Mash}} the television series]] a few years later[[note]]Although, it was an instrumental version[[/note]]. Altman joked that because of music licensing, his son made far more money off the movie than he did!
* Creator/JackieChan sang the main themes for ''Film/PoliceStory'' and ''Film/WhoAmI1998''.
* ''Film/DownWithLove'', at the end of the film, throws in a music video of Creator/ReneeZellweger and Creator/EwanMcGregor performing "Here's to Love" (which is basically the LoveTheme WithLyrics) in character.
* Creator/WillSmith did this multiple times. ''Film/MenInBlack'', ''Film/WildWildWest'', and ''Film/{{Hitch}}'' come to mind as three whose theme songs got lots of radio play as well (the first two [[TitleThemeTune matching the film titles]], the last being called [[SubvertedTrope "Switch"]]).
* The theme song to ''Film/AGunfight'' (also titled "A Gunfight") was written and performed by Music/JohnnyCash, who also starred in the movie.
* ''Film/MarkedForDeath'': Creator/StevenSeagal wrote the song "John Crow". Though it is performed by Jimmy Cliff during the movie, it plays again during the end credits, and Seagal sings the first few lines.
* Eartha Kitt sings "A Knight for My Nights"; the theme song for ''Film/UpTheChastityBelt'', in which she appears as Scheherazade.
* Creator/TuesdayKnight, who played Kristen Parker in ''Film/ANightmareOnElmStreet4TheDreamMaster'', also sang the film's theme tune, [[https://www.youtube.com/watch?v=FGSMSuI34Tk "Nightmare"]].
* ''Film/{{Shrooms}}'': The song "Curveball", featured in the ending credits, was performed by the Rig Brothers, but features vocals by Lindsey Haun (Tara). Additionally, she also co-wrote the song.
* ''Film/SpecialCorrespondents'': The song "Dollar for a Hero" was performed by Creator/VeraFarmiga (Eleanor).
* Creator/TonyLeung and Creator/AndyLau duet the ending song to ''Film/InfernalAffairs''. Both are established and popular singers as well as actors.
* ''Film/{{Fame}}'''s TitleThemeTune was sung by lead actress Irene Cara (Coco Hernandez).
* ''Film/TheYinYangMasterDreamOfEternity'': Deng Lun (Bo Ya) sings "痴情冢/Chī Qíng Zhǒng/Tomb of Infatuation".
* The end credits theme of ''Film/GhostbustersAfterlife'', "Haunted House", is sung by Creator/MckennaGrace, Phoebe's actress.
* In ''Film/StrictlyBallroom'', there's a cover of [[Music/CyndiLauper "Time After Time"]] accompanying Scott and Fran's TrainingMontage. The female vocals are done by Tara Morice, who plays Fran.

[[folder:Live-Action TV]]
* An in-show example for ''Series/BrooklynNineNine'', Peralta is on a case with Captain Holt and wants them to play characters, he's Bret Barley, a cop who hates violence against animals, and Holt is Gerald Jimes, a man who can solve every crime except one-the murder of his wife. Holt dismisses the idea, of course, but it doesn't stop Peralta from singing a song about the two fake detectives.
-->"Look out bad guys, its Barley and Jimes, Barley and Jimes are on the case!"
* Two Franchise/SuperSentai series: ''Series/ChoujuuSentaiLiveman'' and ''Series/KousokuSentaiTurboranger''. Both have their theme songs sang by the actors of their respective Red Rangers.
** ''Series/TokusouSentaiDekaranger'' ending in episodes focused on female rangers, "Girls in trouble! DEKARANGER" were sung by Jasmine & Umeko's actress while the boys act as backing vocalists.
** The EndingTheme of ''Series/HikoninSentaiAkibaranger'', "Ashita wa Akiba no Kaze ga Fuku", is sung by Nobuo's actor Masato Wada.
** In South Korea, the opening of ''Series/PowerRangersDinoForceBrave'' is sung by its five male lead actors.
* ''Franchise/KamenRider'': Going all the way back to [[Series/KamenRider the original]], several series have featured songs performed by members of the cast, usually TheHero or TheLancer. An incomplete listing: ''[[Series/KamenRiderV3 V3]]'', ''[[Series/KamenRiderSuper1 Super-1]]'', ''[[Series/KamenRiderBLACK BLACK]]'', ''[[Series/KamenRiderRyuki Ryuki]]'', ''[[Series/KamenRiderBlade Blade]]'', ''[[Series/KamenRiderKabuto Kabuto]]'', ''[[Series/KamenRiderDenO Den-O]]'', ''[[Series/KamenRiderKiva Kiva]]'', ''[[Series/KamenRiderDecade Decade]]'', ''[[Series/KamenRiderOOO OOO]]'', ''[[Series/KamenRiderGaim Gaim]]'', and ''[[Series/KamenRiderDrive Drive]]''. The special mentions...
** ''Series/KamenRiderDenO'', which pulled RearrangeTheSong a lot, as detailed on that trope's page (and that isn't counting the version of the theme song performed by the four main Imagin).
** ''Series/KamenRiderKiva'', which featured a "limited band" called TETRA-FANG, formed to perform the show's insert songs; series star Koji Seto was the lead singer and recurring ''Kamen Rider'' composer Shuhei Naruse played the keyboard.
** ''Series/KamenRiderDouble'' has an odd case: it doesn't happen normally, but one story arc revolves around a villain rigging an ''Series/AmericanIdol''-style singing contest. Philip (who has a tendency to get wrapped up in new experiences) signs himself and Shotaro up as "The Kamen Singers", and they perform "Finger on the Trigger", one of the show's insert songs.
** ''Series/KamenRiderOOO'': The themes for OOO's seven [[MultiformBalance form changes]] are sung by lead actor Shu Watanabe (Eiji Hino) himself. Two of them are also duets - "Time Judged All" with Ryosuke Miura (Ankh) and "Power to Tearer" with the legendary Akira Kushida (the voice of the [[TransformationTrinket O Scanner]]).
** ''Series/KamenRiderGaim'' features a twist on this, as the theme song for Gaim's SuperMode, "Ranbu Escalation", is actually a duet between lead actor Gaku Sano (Kouta Kazuraba) and Yutaka Kobayashi (who plays TheRival Kaito Kumon). Notably, this is because the song is more about their race for the [[PlotCoupon Golden Fruit]] and serves contrasts their character arcs leading into the final part of the show. Notable, in that, more than any other example in the franchise, while most other examples of this trope are the actors simply singing a song about their character, the lyrics and even the music video make it perfectly clear it's the ''characters themselves'' who are singing. The above mentioned Time Judged All is the one that comes closest to this in terms of a song sung by the characters themselves. Kobayashi performed another collective song ("Never Surrender") alongside Gaku Matsuda & Saku Momose, who played Kaito's teammates Zack and Peko.
** ''Series/KamenRiderExAid'' has a rare [[VillainSong villainous]] example: Hiroyuki Takami, who plays series BigBad Masamune Dan, also sung his insert theme, "Justice".
** ''Series/KamenRiderZiO'''s [[ImageSong image song]] "Zi-O! King of Time!" is sung by the lead actor So Okuno. Not to be outdone, fellow actors Gaku Oshida and Keisuke Watanabe, who play Geiz and Woz, respectively, have their own image songs that they also sing, "Future Guardian" and "Black&White".
* Series/MetalHeroes only has two: The opening of ''Series/BRoboKabutack'', "Kiyoku Tadashiku Kabutack," sang by Kabutack's VA, Creator/TakeshiKusao, and Ichiro Mizuki (Doctor Ben/Doctor Bio) sang the opening to ''Series/JikuuSenshiSpielban''.
* A lot of live-action sitcoms on Creator/DisneyChannel -- ''Series/ThatsSoRaven'', ''Series/CoryInTheHouse'', ''Series/HannahMontana'', ''Series/SonnyWithAChance'', ''Series/GoodLuckCharlie'', ''Series/WizardsOfWaverlyPlace'', ''Series/{{Jonas}}'', ''Series/ANTFarm'', ''Series/{{Jessie}}'', ''Series/AustinAndAlly'', ''Series/LivAndMaddie'', ''Series/IDidntDoIt'', ''Series/GirlMeetsWorld'', ''Series/KCUndercover'', ''Series/{{Bunkd}}'', ''Series/{{Bizaardvark}}''... The list goes on.
** It's easier to list which ones which are aversions of the trope: ''Series/LizzieMcGuire'', ''Series/PhilOfTheFuture'', ''Series/TheSuiteLifeOfZackAndCody''/''On Deck'', ''Series/ShakeItUp'' (sung by Music/SelenaGomez of ''Wizards of Waverly Place'' -- surprisingly she never appeared on ''Shake It Up''), ''Series/DogWithABlog'' (a BGM opening), ''Series/BestFriendsWhenever'' (one of the stars from the show is in the band that sang the OP), ''Series/StuckInTheMiddle'', ''Series/AndiMack'' (sung by Sabrina Carpenter of ''Girl Meets World''), and ''Series/JustRollWithIt''.
%% ** Creator/DisneyXD’s shows tend to avoid this trope more than their sister network does. ''Series/ZekeAndLuther'', ''Series/PairOfKings'', and ''Series/CrashAndBernstein'' are the only shows on the network that play this trope straight. ''Series/ImInTheBand''[='=]s theme is sung by the artist who provides Derek’s singing voice on the show.
* Creator/{{Nickelodeon}} does this a lot, especially during the late 2000's and early 2010's when many shows were vehicles for the stars' budding music careers. Music/MirandaCosgrove sings the theme song to ''Series/ICarly'', Music/VictoriaJustice sings the theme for ''Series/{{Victorious}}'', Music/KekePalmer sings the theme for ''Series/TrueJacksonVP'', Big Time Rush sings the theme for... ''Series/BigTimeRush'', Brec Bassinger sings the theme for ''Series/BellaAndTheBulldogs'', and Kel Mitchell sings the theme to ''Series/GameShakers''. Older Nickelodeon series include the entire cast performing the theme to ''Series/EureekasCastle''.
* ''Series/H2OJustAddWater'''s third season has the original opening song, "No Ordinary Girl", sang by Indiana Evans, the actress playing Bella. Averted with the first two seasons (which were performed by Ellie Henderson in season one and Kate Alexa in season two).
* Not only Torri Webster, who plays Tess, sings "Wonderful Life" for ''Series/LifeWithBoys'' but she also joined by Canadian singer Katia Zuccarelli as a duet theme song.
* British actor Dennis Waterman has a history of doing this with the shows that he's in, including ''Series/{{Minder}}'' and ''Series/NewTricks''. This is spoofed in a recurring skit on ''Series/LittleBritain'', which invariably ends with Waterman losing work because of his insistence that he "write the theme tune, sing the theme tune..." to pretty much every job he's offered. (The other joke is the fact that the "Dennis Waterman" of the show, played by David Walliams, is repeatedly shown to be absolutely tiny, whereas the real Dennis Waterman is 5′9″ -- dead average.) The irony is that, although he sang the theme to ''Minder'', he didn't actually write it. That was done by his wife of the time ''Patricia'' Waterman.
** This parody was parodied on the Comic Relief special, with the real Dennis Waterman invading the Dennis Waterman sketch to point out the inaccuracies, and then sing the show's theme tune anyway.
* In ''Series/{{Frasier}}'', Creator/KelseyGrammer, who stars as the eponymous Dr. Frasier Crane in the show, sings the closing theme song, "Tossed Salads and Scrambled Eggs".
* The first theme to ''Series/TheDrewCareyShow'', "Moon Over Parma", was sung by Drew Carey.
* Creator/JossWhedon wrote the theme song for ''Series/{{Firefly}}''. There's an alternate version of the opening in the DVD boxset where he sings it himself (albeit not that well).
* Creator/GeneRoddenberry wrote the [[ForgottenThemeTuneLyrics lyrics]] to the ''Series/StarTrekTheOriginalSeries'' theme just so he could get 50% of the royalties as a lyricist, and without asking its composer Alexander Courage. Courage felt that Roddenberry's conduct was unethical (although he never pursued any legal action), to which Roddenberry replied "Hey, I have to get some money somewhere. I'm sure not gonna get it out of the profits of ''Star Trek''." This royalty issue, as well as being busy scoring ''Film/DoctorDolittle'', may explain why Courage only scored a few episodes in the first and third seasons.
* ''Series/{{Psych}}'' creator Steve Franks wrote and sang the theme song with his band, The Friendly Indians. He says that of all the times his name comes up in the show's credits, that's the one that makes him the happiest.
* Every iteration of the ThemeTune of ''Series/MysteryScienceTheater3000'' was written and performed by the show's stars - Joel Hodgson wrote the lyrics that appear during his five seasons on the show, and all the variations that appear during the Mike years were written by Mike Nelson himself. (Considering that Mike wrote about three out of every five songs performed on the show, this is not actually all that surprising.) The streak was broken by Season 11, with lyrics written and sung by Har Mar Superstar, albeit with part of the song being sung by Creator/FeliciaDay, who played the show's new BigBad.
* "Final Frontier", the ThemeTune for ''Series/MadAboutYou'' was written by Paul Reiser, who starred in the show. (Note that the show ''also'' featured DiegeticSoundtrackUsage on one occasion.) Reiser also played piano in the recording of the theme song.
* The theme song for ''Series/MimpiMetropolitan'' is sung by Bambang, Alan and Prima's actors with backing vocals from the creative team (who wrote the lyrics).
* The theme tune to the 1970s American sitcom ''Series/{{Alice|1976}}'', "There's a New Girl in Town", was sung by Linda Lavin, who portrayed the title character.
* The theme to the 1980s British sitcom ''A Fine Romance'' (the [[RealSongThemeTune song]] "A Fine Romance", written by Jerome Kern and Dorothy Fields) was sung by the show's star, Dame Judi Dench.
* Creator/ZooeyDeschanel sings the theme song of ''Series/NewGirl''. Her character sings part of the theme song in-universe in the pilot episode, and only by the second episode does the series feature the 'official' song as an opener.
* The theme song for ''Series/HowIMetYourMother'' is sung by The Solids, a band that is made up of four guys, two of which are the show's creators, Carter Bays and Craig Thomas. In a sixth-season episode, the cast ''performs'' the theme song.
* Folk singer John Tams played a regular supporting role in ''Series/{{Sharpe}}'' and also wrote/arranged and sang most of its music.
* Subversion: The theme tune of ''Series/TwoAndAHalfMen'' ''appears'' (in the show's initial opening credit sequence) to be sung by the titular cast, but producer Chuck Lorre confirmed in 2005 at a convention that actors Charlie Sheen, Jon Cryer and Angus T. Jones are only lipsynching. The actual vocals were done by professional studio musicians -- notably, the one for Angus was an uncredited [[Film/PeeweesBigAdventure E.]][[WesternAnimation/{{Rugrats}} G.]] [[CrossDressingVoices Daily]].
** However, a TV spot for the show ''did'' feature the actors actually singing a set of gag lyrics to that title tune -- evidently commemorating its move to daily syndication, as the lyrics began with Charlie Sheen singing, ''"EV-ry day, we're ON ev-ry DAY now..."'' Comparing Sheen's and Cryer's actual singing voices to the sound of the theme ''should'' have put this trope to rest for the show, but unfortunately ViewersAreMorons.
* On the subject of Chuck Lorre, ''Series/TheBigBangTheory'''s theme song, written and performed by the Music/BarenakedLadies, was ''mistaken'' for this by a few people who believed that Creator/JimParsons sang it.
** The same thing happened with ''Series/{{Smallville}}''’s theme song. The lead singer of Remy Zero, the band that performed "Save Me", bears an uncanny resemblance to Michael Rosenbaum (ComicBook/LexLuthor).
** Similarly, some people thought that Richard Sanders sang the ''Series/WKRPInCincinnati'' theme song. But he played Les Nessman and WordOfGod holds that the lyrics were written from the perspective of Andy Travis, who was played by an actor (Gary Sandy) who had singing experience in musicals. It was actually performed by session singer Steve Carlisle.
* The theme tune of ''Series/TwentyOneJumpStreet'' was performed by Holly Robinson, who played Officer Judy Hoffs on the show (with the "JUMP!" shout provided by Johnny Depp and Peter [=DeLuise=]).
* ''Series/WalkerTexasRanger''. Creator/ChuckNorris. "Eyes of the Ranger".
* The two theme tunes of ''Series/OnlyFoolsAndHorses'' are sung by John Sullivan, the series creator.
** Something that some people have noticed about the way Sullivan sings it is that he sounds like one of the main characters, Rodney. A few people did indeed think that Nicholas Lyndhurst was the one singing it.
* Parodied in ''Series/GarthMarenghisDarkplace'': The opening is "based on melodies originally whistled by Gath Marenghi".
* Both ''Series/TheHoneymooners'' and ''The Jackie Gleason Show'' featured theme music written by Creator/JackieGleason himself (Gleason put out numerous albums, but as a conductor rather than a singer).
* David Naughton (better known as the "Dr. Pepper" guy and as ''Film/AnAmericanWerewolfInLondon'') both starred in and sang the theme song for the shortlived 1978 sitcom, ''Makin' It''. Ironically, though the show was a flop, the song was a hit.
* The theme song for ''Series/RoundTheTwist'' was sung by Tamsin West, who played the original Linda.
* Creator/CraigFerguson sings the theme song for his late-night chat show ''Series/TheLateLateShow With Craig Ferguson'', and also co-wrote the lyrics. And yes, he's really playing the drums in the opening segment.
* Carroll O'Connor wrote the (never heard on the show) lyrics to "Remembering You," the closing instrumental theme song for ''Series/AllInTheFamily''. Also, of course, the opening theme "[[https://www.youtube.com/watch?v=oV5LQcmuGg8 Those Were The Days]]" was sung (on camera) by O'Connor and Jean Stapleton.
* Paul [=McDermott=], host of ''Series/GoodNewsWeek'', sings the theme tune (a cover of Hedgehoppers Anonymous' ''Good News Week'').
* The famous ThemeTuneRap to ''Series/TheFreshPrinceOfBelAir'' was performed by... [[Music/DJJazzyJeffAndTheFreshPrince DJ Jazzy Jeff and]] [[Creator/WillSmith the titular Fresh Prince.]]
* The theme tune for the first season of ''Series/{{Campion}}'' was sung by lead actor Creator/PeterDavison.
* The theme song to ''Series/{{Reba}}'' is somewhere between this and RealSongThemeTune, since it's a partial rewrite of Music/RebaMcEntire's 2002 single "I'm a Survivor".
* [[Series/TopGearUK James May]] wrote the theme tune to his own series, ''Series/JamesMaysManLab''. Given his musical background, it's not terribly surprising.
* The opening theme from ''Series/{{Bottom}}'' was written and performed by The Blue Notes, Creator/AdrianEdmondson's band. They also played the cover of "Last Night" that runs under the closing credits.
* Beginnning in its second season, ''Series/TheBradyBunch'' had its theme song performed by the show's six child actors (as well as that of ''WesternAnimation/TheBradyKids''.)
* Lee Majors sang the theme song from ''Series/TheFallGuy'', "The Unknown Stuntman" (co-written by the show's creator, Glen A. Larson, who wrote or co-wrote the themes for many of his shows and thus paved the way for Creator/JJAbrams).
* ''Series/EverybodyHatesChris'' almost had one of these. Cast member Tichina Arnold wrote and performed her own song, but ultimately an instrumental theme tune was chosen instead. A small snippet of the song became the iconic "Everybody Ha-ates Chris!" riff at the act-breaks and [[EveryEpisodeEnding end of every episode]].
* Greg Evigan shares ownership of this trope with Dennis Waterman, having done this ''four'' times, first with shortlived '70s sitcom ''Series/AYearAtTheTop'' - justified as it was a show about a pair of musicians, played by Evigan and Paul Shaffer (!) - then with ''Series/BJAndTheBear'', ''Series/MyTwoDads'' (which he also performed on screen in one episode, leading Paul Reiser to wonder where he'd heard that song before) and ''[[https://www.youtube.com/watch?v=A6QB2Y22mAs P.S. I LUV U]]''.
* The ''Series/{{Rentaghost}}'' theme tune was written and sung by Michael Staniforth, who played Claypole on the show.
* ''Series/PowerRangersDinoThunder'' executive producer Douglas Sloan co-wrote its theme song.
* ''Series/UltramanLeo'' has its first theme song performed by main star Ryu Manatsu. He did a rerecording a few decades later.
* Nell Carter sang the theme song for ''Series/GimmeABreak''.
* Music/WaylonJennings should be considered part of the cast for ''Series/TheDukesOfHazzard'', right? He sings the theme song (a.k.a. "Good Ol' Boys") ''and'' he narrates each episode.
* Music/QueenLatifah performed the theme for ''Series/LivingSingle''.
* Cybill Shepard sings the theme to ''Series/{{Cybill}}'' herself.
* Marla Gibbs sings "There's No Place Like Home", the theme tune to ''227'' of which she is the star.
* ''Series/{{Watching}}'' begins and ends with ditties sung by Emma Wray in-character as Brenda.
* Creator/MervGriffin frequently did this with his GameShow properties:
** He composed the theme song and JeopardyThinkingMusic for the original 1964-1974 version of ''Series/{{Jeopardy}}'' When the show was brought back in 1984, an adaptation of the latter became the show's BootstrappedTheme, which is still used in rearranged form to this day.
** Originally averted with ''Series/WheelOfFortune'', which [[EarlyInstallmentWeirdness originally]] used Creator/AlanThicke's "Big Wheels", but changed to Merv's own "Changing Keys" in 1983. During most of the 80s and 90s, Merv also composed various music beds used throughout the show (one of which was later {{Recycled|Soundtrack}} many years later, shortly after Merv's death, for ''Series/MervGriffinsCrosswords''). Versions of "Changing Keys" were used until 2000, when they were replaced by different composers' themes.
** Going a little further back, Griffin wrote the theme for the first game show he produced, 1963's ''Word For Word''. Griffin hosted the show as well.
** Griffin also composed the theme for ''Series/HeadlineChasers'', which was created by [[Series/TicTacDough Wink Martindale]] but put out by Griffin's production company.

* The original Swedish version of the 1969 ''Literature/PippiLongstocking'' series had Inger Nilsson (who plays Pippi) sing the theme song.[[note]]Which only appeared in the closing credits. It originally didn't have an opening sequence; those were added by the German and English versions (the latter of which was released as four movies in the U.S.).[[/note]]
* The theme tune to ''Series/{{Taskmaster}}'' is performed by The Horne Section, which is co-host Alex Horne's band.
* During the 1989-1990 season, Los Angeles-based KTTV's weekday afternoon programming block was known as "[[Franchise/{{Mario}} King Koopa]]'s Kool Kartoons"[[note]]They were airing ''Series/TheSuperMarioBrosSuperShow'' during this time.[[/note]], which was also the name of a local show that aired at the end of each day. This show had a theme song performed by Christopher Collins (AKA: [[WesternAnimation/GIJoeARealAmericanHero Chris]] [[WesternAnimation/TheTransformers Latta]]) who was (at least) the voice of this version of "King Koopa" (as he was called in the animated show)[[note]]Later on in the show's run, he was replaced by Pat Pinney, best known as the voice of WesternAnimation/MightyMouse in Ralph Bakshi's ''Mighty Mouse: The New Adventures''.[[/note]].

* The main theme of ''Series/ElCorazonNuncaSeEquivoca'' is performed by Emilio Osorio and Joaquín Bondoni, who also play the main characters.
* Creator/DavidCassidy sang both versions of ''Series/ThePartridgeFamily'''s theme song.
* The theme song for ''Series/BigBadBeetleborgs'' was sung by Billy Forester, who played Flabber.
* [[https://www.youtube.com/watch?v=-vX9XxTAFwM Parodied]] in a ''Series/SaturdayNightLive'' sketch where the stars of popular television shows sing to their theme tunes WithLyrics, such as Jim Hopper singing the tune of ''Series/StrangerThings,'' Cousin Greg singing to the ''Series/{{Succession}}'' theme (which is just him repeating "Huh? What?" over the music), and Baby Yoda rapping the theme song of ''Series/TheMandalorian'' before quitting because he doesn't like the beat. They cap it off with the real Creator/JohnKrasinski (the episode's host) singing his own lyrics to ''Series/TheOfficeUS'', which borders on a LiteralMusicVideo.

[[folder:Pro Wrestling]]
* Wrestlers in TheEighties often sung their own songs such as The Fabulous Rougeau Brothers (Wrestling/{{Jacques|Rougeau}} and Raymond), Wrestling/HillbillyJim, and [[Wrestling/HonkyTonkMan the Honky Tonk Man]].
* Manager Wrestling/JimmyHart was once the Trope Namer for SuspiciouslySimilarSong due to all the songs he's written when employed by various promotions.
* Michael Hayes wrote and sang The Freebirds' "Badstreet U.S.A."
* Wrestling/ShawnMichaels sang his own theme song after he broke off with the previous singer and his then-manager, [[Wrestling/SherriMartel Sensational Sherri]]. He used the same song for over a decade [[TheArtifact despite having dropped the "sexy boy" gimmick it was originally written for]], and kept it right until retirement.
* Borderline examples but there's a whole host of wrestlers whose catchphrases make it into their themes, usually at the beginning. Notable examples include [[Wrestling/DwayneJohnson The Rock]], New Age Outlaws, Wrestling/{{Carlito|Colon}}, Finlay, Wrestling/TheMiz, Wrestling/ZackRyder, Wrestling/{{Ryback}}, Wrestling/BraunStrowman, Woken Wrestling/MattHardy, [[Wrestling/EthanCarterIII EC3]] and Wrestling/MattRiddle.
* [[Wrestling/RonKillings R-Truth]] not only raps his own theme but puts on a live performance of the theme as part of his entrance. He's done this pretty much ever since he started wrestling, having done so in [[Wrestling/ImpactWrestling TNA]] as Ron Killings and in his first WWF stint as K-Kwik.
* JD dojo graduate and Pro Wrestling Wave ace Yumi Ohka has TheGimmick of an idol who not only sings her own entrance themes but will interrupt shows to put on performances.
* Wrestling/JohnCena, due to the rapper gimmick he used to have, made his last two themes, one of which is still being used (over a decade later!) despite, as with Michaels, having long since dropped the gimmick.
* The WWE produced an album called ''WWE Originals'' which were songs all sung by the wrestlers or divas on the roster. Some were used briefly as actual themes for the respective wrestlers; briefly because, despite the valiant efforts of [[SugarWiki/AwesomeMusic Jim Johnston]], the world learned that professional wrestlers do not make for great singers (except Wrestling/ChrisJericho, who already was a singer and Lillian Garcia, whose not a wrestler) Well, despite "Put A Little Ass On It" being laughably terrible, Wrestling/{{Rikishi}} did happen to be a REALLY good singer and John Cena's "Basic Thuganomics did have some longevity"(but that's rapping, not singing)
* Wrestling/JeffHardy's theme songs in TNA are written & performed by him. They were performed with his band Peroxwhy?gen.
* Wrestling/JimmyJacobs recorded several songs in Wrestling/RingOfHonor, particularly during his contributions to the Lacey's Angel's angle where he was expressing his love to the not so Lovely Lacey.
* Wrestling/ShannonMoore's final WWE theme song was an instrumental of a song he'd written & recorded.
* Wrestling/JillianHall sings her theme music "Sliced Bread," which adds to [[HollywoodToneDeaf her gimmick of being an absolutely AWFUL singer.]]
* Wrestling/MickieJames did her own theme song after leaving WWE, and since she's at worst decent, it heightened her rivalry with the similarly released Jillian Hall.
* Wrestling/ChrisJericho's band, Music/{{Fozzy}}, has had their songs as themes for a few of WWE's pay-per-view events, most recently "Martyr No More" for the 2010 Royal Rumble. He never used a Fozzy song as his own theme in WWE, but has used "Judas" in other promotions.
* Wrestling/MontelVontaviousPorter went out and recorded his second WWE entrance theme without in put from the company. They, accordingly, [[ChorusOnlySong played nothing but the chorus of it]], though Wrestling/NewJapanProWrestling not only played the whole thing but remixed the beat and even added Godzilla's roar to the track. He then used one of his already released themes for his youtube sessions, did another for his New Japan run with [[Wrestling/TheWorldsGreatestTagTeam Shelton Benjamin]] and did a another two themes for his [[Wrestling/ImpactWrestling TNA]] run—one for himself, one for his Beat Down Clan PowerStable.
* [[Wrestling/CarleneMoore Jazz]]'s SHINE Wrestling debut was also the debut of a theme she made for herself.
* Rocky Romero did the RPG Vice theme in New Japan in tribute to Alex Koslov.(Beretta helped)
* Caprice Coleman lent his voice for his own individual theme in Wrestling/RingOfHonor, though his C&C TagTeam theme is done by King Kelezy.
* Wrestling/MariaKanellis performs her own theme song on the independent circuits, the titular track of her album ''Sevin Sins'' which she released through Zombie Entertainment.
* Mark Andrews of TNA & Progress Wrestling co-wrote his own theme song, as it is a track by his band Junior (he is the bassist and co-lead vocalist). The band themselves recently fully acknowledged Mark's wrestling background by creating a music video which was entirely wrestling themed, including a cameo appearance from [[Wrestling/MattHardy Broken Matt Hardy]]!
* Wrestling/{{Cameron}} not only recorded "Girl Bye", her entrance theme, she recorded a music video of it!
* Wrestling/TheUsos, Starting August 1, 2017, The Usos rapped their own theme song using a variety of catchphrases during their current {{heel}} run, this would later be known as the Day One remix of "Done With That".
* Wrestling/TylerBreeze "Sings" the lyrics to "#Mmmgorgeous", which basically amounts to Tyler talking about how really really really ridiculously good looking he is.
* Wrestling/TheShield, The words "Sierra Hotel India Echo Lima Delta. Shield." from their opening theme? Recorded by the guys themselves.
* Wrestling/KeithLee raps his own NXT theme song "Limitless" and his current main roster theme song "Born to Bring It".
* Wrestling/BrayWyatt, Parts of his new theme, Let Me In, were done by Wyatt himself — specifically, the "Yowie wowie!" and "Let me in!" spoken portions in the beginning. But the outro phrase, "I'm really sorry what I did. (Let Me In)", were done by both Wyatt and Music/CodeOrange.
* Wrestling/ScarlettBordeaux, her and Karrion Kross NXT theme song Dead Silent is sung by herself.
* Wrestling/{{Elias}}, his theme song Amen (I'm Going In) is sung and played guitar by himself.

[[folder:Puppet Shows]]
* Creator/JimHenson seemed to loved this trope, as it also happens in ''Series/TheMuppetShow'', ''The Ghost of Fafner Hall'', and others[[note]]But not ''Series/SesameStreet''.[[/note]].
** ''Series/BearInTheBigBlueHouse'''s theme is sung by the main characters.
** ''Series/FraggleRock'''s theme is a CrowdSong sung by most if not all of the Muppet performers, including the main cast.

* Two other CrowdSong examples are both the opening and [[MemeticMutation ending]] themes to ''Series/LambChopsPlayAlong'' which are sung by Shari Lewis (both as herself, and as her three characters Lamb Chop, Hush Puppy and Charlie Horse), and by various kids.
* The ''Series/ElmosWorld'' theme song is sung by Elmo himself.
* ''Series/TheNoddyShop'' opens with a song sung by the toys that live in the shop. This is actually justified, considering that their songs are a major part of the show, as they usually get the moral across.
* While a woman sings most of the song, the final part of the ''Series/DonkeyHodie'' theme song is sung by the entire cast.

[[folder:Video Games]]
* ''VideoGame/{{Portal}}'':
** The ending theme to ''VideoGame/Portal1'' is sung by Creator/EllenMcLain in character as [=GLaDOS=], complete with the electronic voice distortion and unsettling inflections of the original. Keep in mind that [=McLain=] is a trained opera singer.
** Which gets shown much more [[spoiler:with the singing turrets (whom she also voices) and the ending theme of ''VideoGame/Portal2'']]. The author of both ending themes, Music/JonathanCoulton, didn't know who he was writing for the first time around. For the second game, he knew who [=McLain=] was and thus wrote much more vocally complex song, taking advantage of [=McLain=]'s considerable singing talents.
* ''Franchise/MegaMan'':
** The opening theme in the original Japanese release of ''VideoGame/MegaManX5'', "Monkey", is sung by Creator/ShowtaroMorikubo, who also voiced X.

* In ''VideoGame/CorpseParty'', the openings of ''Blood Covered... Repeated Fear'', ''Book of Shadows'' and the ''Tortured Souls'' OVA ([[https://www.youtube.com/watch?v=0ZNSuSyo6gk Shangri-La]], [[https://www.youtube.com/watch?v=iSTVrZFfJBM Where Flowers Bloom]], [[https://www.youtube.com/watch?v=yXVnap7Zb2o Ring of Stardust]]) and the 2nd opening of ''Blood Drive'' ([[https://www.youtube.com/watch?v=8_VrGGnFx2U Incarnation]]) are sung by Creator/AsamiImai, who voices [[ClassRepresentative Ayumi]] [[UnwittingInstigatorOfDoom Shinozaki]]. On a particular note, she made duets with Creator/EriKitamura (who voices [[WomanChild Yuka]] [[OlderThanTheyLook Mochida]]) under the name ARTERY VEIN for the endings of the three main games ([[https://www.youtube.com/watch?v=vcsPgyOp6a0 Prayer of Confutatis]], [[https://www.youtube.com/watch?v=fnOHbC29zTk Pandora Night]], [[https://www.youtube.com/watch?v=ZSiKgnPYXAE Translucent Days]]) and an insert song for ''Blood Covered...

* ''VideoGame/SuperRobotWars [[VideoGame/SuperRobotWarsOriginalGeneration OG Saga:]] [[VideoGame/EndlessFrontier Endless Frontier EXCEED]]'' main heroine is voiced by Creator/NanaMizuki. And given her recent popularity, it wasn't a surprise that she sings the opening theme for the game.
* In the ''VisualNovel/TokimekiMemorial'' series, the openings and endings of all Hibikino Saga games (''Tokimeki Memorial 2'' and its spin-offs) save for ''Leaping School Festival'' (and ''Dancing Summer Vacation'' for the endings) are sung by Creator/JunkoNoda, the voice actress of the Hibikino Saga's main heroine Hikari Hinomoto.

* ''VideoGame/{{Shantae}}'' has "Dance Through the Danger", as well as the opening song for ''VideoGame/ShantaeAndTheSevenSirens'', performed by the titular character's voice actress [[Creator/CristinaValenzuela Cristina Vee]], who's presumably singing them in-character based on the lyrics.
* ''VideoGame/ToeJamAndEarl'' series creator Greg Johnson composed and sang the 1991 promo rap on cassette tape.

[[folder:Web Animation]]
* ''VideoGame/{{Bravoman}}'':
** While the show doesn't have Bravoman himself sing the theme tune, one episode features him firing the show's sound department in order to defeat a cyborg ninja ([[ItMakesSenseInContext long story]]). Since there's nobody to play the ending theme, Bravoman sings it himself.

* Most of ''WebAnimation/CampCamp'''s soundtrack is sung by Creator/RoosterTeeth employees, including the rather...[[PatterSong difficult]] opening theme, which is sung in-character by creator Miles Luna, who voices the character David. To his despair, the song is often requested at his panels.
* ''WebAnimation/{{Hololive}}'': "[[https://www.youtube.com/watch?v=5y3xh8gs24c Excuse My Rudeness, But Could You Please RIP?]]" is definitively Mori Calliope's most known work as a musical artist, and a theme tune to an extent considering [[SpeedyTechnoRemix remixes of it]] appear at the beginning and end of her streams.
** To a lesser extent, "[[https://www.youtube.com/watch?v=eDfMDkgheQY HINOTORI]]" is Kiara's, performed by the phoenix herself.

* Brendon Small was responsible for nearly all the music on ''WesternAnimation/HomeMovies'', including the theme song. He also writes the music for ''WesternAnimation/{{Metalocalypse}}'' and voices three of [[FakeBand Dethklok's]] five members, including lead singer Nathan Explosion.
* One of the {{DVD commentar|y}}ies for ''WesternAnimation/{{Futurama}}'' has Creator/BillyWest (in character as [[CloudCuckoolander Fry]]) state that the theme song needed lyrics and sing the word "Futurama" in time to the music over the end credits.
* The Creator/{{Disney}} series ''WesternAnimation/PepperAnn'' has Kathleen Wilhoite, voice actor for the titular character, sing the theme song.
* The first run of American dubbed episodes of ''WesternAnimation/BobTheBuilder'' have William Dufris, original American voice actor for the titular character, sing the theme song.
** The original UK version had its theme tune sung by Neil Morrissey.
* The ''WesternAnimation/VeggieTales'' theme song is sung by the show's cast.
* ''WesternAnimation/SonicUnderground'', to the extent that a single spoken line in the middle of the song from Queen Alina ("I long for my children but I have to wait. To act too soon could seal their fate.") is done by that character's voice actress.
* ''WesternAnimation/AsToldByGinger'''s theme was done by Ginger's voice actress, Melissa Disney, for the pilot episode, but was replaced by Miranda's voice actress Cree Summer and later R&B singer Macy Gray. In the US, the first few episodes used the Summer theme, but was soon changed to the Gray version even for reruns of the first episodes.
* ''WesternAnimation/LittlestPetShop2012'' has Creator/AshleighBall singing the theme song as her character, Blythe Baxter.
* ''WesternAnimation/TheNewAdventuresOfWinnieThePooh'' has a version of the opening sung by [[https://www.youtube.com/watch?v=pblJhXr1Qms Jim Cummings, out of character]]. This intro was mainly heard in syndicated reruns during the early 90s.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'''s theme song is an interesting case, as most of the main characters have separate speaking and singing voices; as such, the trope is subverted by Twilight Sparkle, Pinkie Pie and Rarity, but played straight with Rainbow Dash, Applejack and Fluttershy.
** A slightly weird example of this trope, as Pinkie Pie and Fluttershy [[Creator/AndreaLibman share a voice actress]].
** Except where the individual main characters chime in with their solo lines, the majority of the theme song (and all of the two-minute version) is sung by Creator/RebeccaShoichet (Twilight) and Shannon Chan-Kent (backup vocals).
** The Japanese dub also falls into this, as the first and third openings, "Mirai Start" and "Yumemiru! Shinjiru! Mirai Kanaete!" are sung by Pinkie Pie's dub VA, Suzuko Mimori.
* Bella Ramsey, the voice of WesternAnimation/{{Hilda}}, wrote and performed a song called "The Life of Hilda" which is a fun combination of this trope and a IAmSong which talks about Hilda's everyday life. While the song is released on Youtube on November 25th, the song was featured as a stinger at the very end of the credits of "The Beast of Cauldron Island". Bonus points for it being sung in her character's voice!
* The theme for ''WesternAnimation/FamilyGuy'' is sung by the voice actors of the Griffin family.
** Also, Mike Henry, who voices Cleveland, appropriately sings ''WesternAnimation/TheClevelandShow'' theme.
** Creator/SethMacFarlane, as Stan Smith, sings the ''WesternAnimation/AmericanDad'' theme song.
* The theme song from ''WesternAnimation/SouthPark'' features lines by Stan and Kyle, Cartman, and an unintelligible one by Kenny. (the latter replaced by Timmy singing his own name in season 6)
* ''WesternAnimation/JaneAndTheDragon'' has Jane singing part of the theme song.
* The ''WesternAnimation/HongKongPhooey'' theme song was sung by his voice actor, Benjamin "Scatman" Crothers.
* ''WesternAnimation/DastardlyAndMuttleyInTheirFlyingMachines'': Creator/PaulWinchell performed the theme song in character as Dick Dastardly.
* ''WesternAnimation/{{Animaniacs}}''. The theme song is mostly sung by the Warners, with the last set of lines sung [[CrowdSong by the entire cast]]. In [[WesternAnimation/Animaniacs2020 the revival]], only the Warners sing the entire song, since most of the other cast members are now gone.
* The Season 3 outro of ''WesternAnimation/{{Amphibia}}'' is a vocaloid remix of "Anne's Theme" performed by Brenda Song, Justin Felbinger, Bill Farmer, and Amanda Leighton, which remixed lines from past episodes including the classic, "Not the baby!" from "Marcy At The Gates".
* ''WesternAnimation/TheMask'' not only has the theme performed by Rob Paulsen, but the way he sang almost sounds similar to Yakko's...
* The ''WesternAnimation/TinyToonAdventures'' theme song is technically another crowd song, but is mostly sung by Buster and Babs Bunny ([[RunningGag no relation]]), with Plucky joining in for a few lines.
* The theme tune for ''WesternAnimation/WatchMyChops'' uniquely combines this with ExpositoryThemeTune: Corneil (a talking dog) starts out singing the theme tune on his own, until dogsitter Bernie comes in, realizes Corneil can talk, and most of the rest of the song is a duet that sums up the premise of the show (Bernie must hide the fact that Corneil can talk from everybody else).
* The theme song for ''WesternAnimation/{{Hammerman}}'' is sung by Music/MCHammer himself.
* The theme for ''WesternAnimation/TheCatInTheHatKnowsALotAboutThat'' is written and sung by the show's music composer David Schweitzer who sings in an American accent.
* ''WesternAnimation/AdventureTime'':
** The regular theme is sung by creator Creator/PendletonWard, who [[DescendedCreator also voices some characters]], mostly notably Lumpy Space Princess.
** Each of the three miniseries has a SpecialEditionTitle where the theme is sung by the character most in focus: Marceline in ''Stakes'', Finn in ''Islands'', and Princess Bubblegum in ''Elements''.
** The Japanese dub has the opening performed by Finn and Jake's dub [=VAs.=] Becomes funny when you remember Finn's dub voice is Creator/RomiPark, the voice of [[Manga/FullmetalAlchemist Edward Elric.]]
* ''WesternAnimation/TangledTheSeries'' uses a shorter version of "The Wind In My Hair" from the pilot episode as the show's intro, sung by Rapunzel's voice actor, Music/MandyMoore.
* ''WesternAnimation/SofiaTheFirst'' is another one to mash-up this and ExpositoryThemeTune, as the title song is done by Sofia's voice actor, Creator/ArielWinter.
* ''WesternAnimation/TheCasagrandes'''s theme is sung by Izabella Alvarez in character, joined by Ally Brooke as part of a duet as well as Ronnie Anne's family. You can't have a good family theme song without your familia.
* The theme for ''WesternAnimation/StevenUniverse'' is sung by the main cast, in-character. Due to the [[MusicalWorldHypotheses diegetic]] nature of many songs in the series, it is even part of the show's canon, as a song that the titular character wrote as a child.
* ''WesternAnimation/TheHairBearBunch'' theme is performed by the voice actors of the bears--Daws Butler (Hair Bear), Paul Winchell (Bubi), and Bill Calloway (Square).
* The theme for ''The Scooby Doo-Dynomutt Hour'' (1976) originally had the voice actors (Frank Welker, Casey Kasem, Pat Stevens, Heather North) performing the theme. When the Scooby episodes were prepped for syndication in 1980, the opening was revamped without Dynomutt and the voice actors replaced doing the theme (with new lyrics) by unidentified performers.
** When Dynomutt got his own half-hour, the theme for it was expanded from the segment intro on ''Scooby-Doo/Dynomutt'' and was performed (spoken) by the two main voice actors, Gary Owens and Frank Welker.
* ''WesternAnimation/{{Grojband}}'' frontman Corey Riffin gives us a catchy little expository tune at the beginning of each episode to explain what his band does.
* ''WesternAnimation/{{Caillou}}'''s theme song is sung by the titular character.
* WesternAnimation/LittleEinsteins' theme song was sung by the main four characters.
* The opening to ''WesternAnimation/TheGhostAndMollyMcGee'' is performed by Creator/AshlyBurch and Creator/DanaSnyder who voices Molly and Scratch respectively. Molly sings about how Scratch is stuck with her forever and [[ThisIsGonnaSuck Scratch goes on about on how it will go wrong]].
* ''WesternAnimation/StarVsTheForcesOfEvil'': The ending theme for the first two seasons is performed by Star's voice actress, Eden Sher. Bonus points because it feels like an anime ending (both visuals and song-wise).
* ''WesternAnimation/{{Chowder}}'''s theme is sung by its main cast in-character. Since this includes [[TheUnintelligible Shnitzel]], one of the lines ends up being "Radda radda radda, ra-ra radda radda!"[[note]]Which translates to "You share a big piece with everyone."[[/note]]
* The credits song from ''WesternAnimation/RugratsGoWild'' is performed by [[Creator/ElizabethDaily E.G. Daily]] and ''WesternAnimation/AllGrownUp'''s opening theme is performed by Creator/CreeSummer, both out of character.
* The opening theme of the 1997 ''Literature/PippiLongstocking'' animated series, "What Shall I Do Today?", is performed by Pippi.
* Peg and Cat almost entirely sing the TitleThemeTune of ''WesternAnimation/PegPlusCat'', save that off-screen kids sing the parts with the numbers and also join for the final shouting of the title.
* In ''WesternAnimation/EllaTheElephant'', the theme song is sung in-character by Ella, though some of the other characters join at times.
* The theme to ''WesternAnimation/IHeartArlo'', which is simply an abridged version of "Beautiful Together" from the PilotMovie, is indeed performed by Arlo's voice actor Michael J. Woodard.
* ''WesternAnimation/SheriffCalliesWildWest'' has its theme mostly performed by its title character, Sheriff Callie. "''Hey, I'm Callie, and I'm the sheriff, got my badge here on my vest!''"
* The ''WesternAnimation/CatDog'' theme was written and sung by Peter Hannan, who also served as the show's executive producer and main character designer.
* The theme song to ''WesternAnimation/MiloMurphysLaw'' is performed by Music/WeirdAlYankovic, Milo's voice actor.
* The theme song for ''WesternAnimation/BeatBugs'', "[[RealSongThemeTune All You Need Is Love]]" by Music/TheBeatles, is performed by the show's main cast.
* In 1989, Creator/JohnCandy created and starred in an animated series called ''WesternAnimation/CampCandy''. He also sang the show's opening theme song.
* The theme song to ''WesternAnimation/ScaredySquirrel'' is sung by Scaredy himself, though not really singing, but rather scatting the instrumentals.
* ''WesternAnimation/{{Doki}}'' 's theme song is sung by him and his friends.
* ''WesternAnimation/ReadyJetGo'''s theme song is sung by the creator, Creator/CraigBartlett, and part of it is performed by the characters.
* Though it's not the case with the actual show, stage productions of ''WesternAnimation/PAWPatrol'' often have Ryder perform the theme song, replacing the line "Ryder and his team of pups" with "Me and all my team of pups".
** The Japanese version of the theme is performed by the voice actors for the pups.
* The theme song to ''WesternAnimation/ButtUglyMartians'' is sung by Creator/CharlieSchlatter, Creator/RobPaulsen, and Creator/JessHarnell, who are the respective voice actors of B-Bop A-Luna, [=2T=] Fru-T, and Do-Wah Diddy.

* On ''WesternAnimation/FancyNancy'', Nancy's voice actress, Mia Sinclair Jenness, performs almost all of the theme tune, "Add a Little Fancy."
* A strange example happened with ''WesternAnimation/SpongeBobSquarePants'': While Painty the Pirate (aka [[spoiler:Burger Beard]]) usually only shows up for some brief scenes (or the occasional in-show parody of theme song), the kids who co-sang the theme song played some minor roles in the earlier seasons prior to them hitting puberty.
* ''WesternAnimation/KungFuPandaLegendsOfAwesomeness''' theme song (see video example below) is sung by Mick Wingert as Po himself known to be... [[SpoilerTitle Do I even have to say it?!]]
* ''WesternAnimation/TransformersAnimated'': In the Japanese dub of the final episode, the dubbing cast sings along with the dub's intro theme, "TRANSFORMERS EVO." by Music/JamProject.
* ''WesternAnimation/ElinorWondersWhy'' - the theme tune is performed by Elinor, ''except'' for the parts with the [[TitleThemeTune title of the show]], which are sung by a group of kids.
* The second version of ''WesternAnimation/TheRaccoons''' theme tune, "Run With Us"(Stephen Lunt sang the first version), was performed by Lisa Lougheed, the voice actress of [[TheDanza Lisa Raccoon]].
* The theme tune to ''WesternAnimation/CornAndPeg'' is mostly performed by Michela Luci and Kingsley Marshall, but it has parts sung by Corn and Peg.
* ''WesternAnimation/TheBackyardigans'', being a musical show, has its theme tune sung entirely by its main cast (who also dance to it).

* Creator/NanaMizuki does this a lot, with examples including ''Anime/BloodC'' (endings), ''Anime/DogDays'' (openings), ''Manga/RosarioPlusVampire'' and ''Anime/SenkiZesshouSymphogear'' (openings), to name a few.
* The ''Anime/DogDays'' endings are sung by Creator/YuiHorie, and the ''Anime/SenkiZesshouSymphogear'' endings are sung by Creator/AyahiTakagaki. In the latter series, if something else is played instead of the usual ending theme, it's an ImageSong of a character.

** ''Series/KamenRiderOOO'': The themes for OOO's seven [[MultiformBalance form changes]] are sung by lead actor Shu Watanabe (Eiji Hino) himself. Two of them are also duets - "Time Judged All" with Ryosuke Miura (Ankh) and "Power to Tearer" with the legendary Akira Kushida (the voice of the [[TransformationTrinket OOO Driver]]).
** ''Series/KamenRiderGaim'' features a twist on this, as the theme song for Gaim's SuperMode, "Ranbu Escalation", is actually a duet between lead actor Gaku Sano (Kouta Kazuraba) and Yutaka Kobayashi (who plays TheRival Kaito Kumon). Notably, this is because the song is more about their race for the [[PlotCoupon Golden Fruit]] and serves contrasts their character arcs leading into the final part of the show. Notable, in that, more than any other example in the franchise, while most other examples of this trope are the actors simply singing a song about their character, the lyrics and even the music video make it perfectly clear it's the ''characters themselves'' who are singing. The above mentioned Time Judged All is the one that comes closest to this in terms of a song sung by the characters themselves. Kobayashi performed another collective song ("Never Surrender") alongside Gaku Matsuda & Saku Momose, who played Kaito's teammates Zack and Peco.
** ''Series/KamenRiderExAid'' has a rare villainous example: Hiroyuki Takami, who plays series BigBad Masamune Dan, also sung his insert theme, "Justice".

* All three seasons of ''Anime/{{Free}}'' had the ending themes sung by the voice actors for [[Creator/NobunagaShimazaki Haru]], [[Creator/TatsuhisaSuzuki Makoto]], [[Creator/TsubasaYonaga Nagisa]], [[Creator/DaisukeHirakawa Rei]] and [[Creator/MamoruMiyano Rin]], under the name Style Five. Also, both opening themes were performed by the band Oldcodex, which is fronted by Creator/TatsuhisaSuzuki, the voice actor for Makoto.

* ''VideoGame/{{Shantae}}'' has "Dance Through the Danger", as well as the opening song for ''Seven Sirens'', performed by the titular character's voice actress [[Creator/CristinaValenzuela Cristina Vee]], who's presumably singing them in-character based on the lyrics.

* In ''WesternAnimation/IceAge4ContinentalDrift'', Keke Palmer's song "We Are" is played over the credits, with the main cast singing along (Keke Palmer voices Peaches, by the way).

* ''Series/{{Grownish}}'''s theme song "Grown" is performed by band Chloe x Halle, who are also cast members on the show.

* Creator/TonyLeung and Creator/AndyLau duet the ending song to Film/InfernalAffairs. Both are established and popular singers as well as actors.
* ''Film/{{Fame}}'''s TitleThemeTune was sung by lead actress Irene Cara(Coco Hernandez).

* The ending theme for ''Anime/{{Betterman}}'', Chin Requiem, is sung by the show's director, Yoshitomo Yonetani, under the name Mai.
