"Hey, Justin...we feel like you need something hip-hoppy in your video. You know any rappers? "You're listening to a pop song, when suddenly, out of nowhere, a rapper jumps into the song. Then, almost as suddenly as he appeared, he disappears into the night, and the song returns to normal. It can be, but is not necessarily, a rapping bridge. This is generally due to deals made by record companies to promote both artists. Or, more simply, the two could be genuine friends who work together all the time. Such songs are often bowdlerised on the radio, when the entire rap verse is deleted even if it contains nothing questionable, as if the musical concept itself is offensive (or maybe because the station figures their listeners don't like rap). This happens a lot during eras when Top 40 and urban radio don't have a lot of crossover artists — it's an attempt by labels to tentatively promote pop artists to a more urban audience and vice versa without committing to a verse they can't remove. Don't be surprised to find the pop singer returning the favor by singing the hook in a later song by said rapper. A similar practice existed in the early 1940s (which could be called A Wild Texan Appears), where a guy with a southern accent suddenly started talking over the music without warning. The trope name is a pun on a line in the Pokémon games "A wild <Pokémon> appeared!", which has become a meme with the verb in the present tense "appears".

Anime & Manga
- In an episode of Samurai Champloo, a trio of local villagers come out of nowhere and start rapping about recent events, and then leave equally abruptly, leaving the protagonists just as confused as the viewer.
- The full version of Ryuko's Leitmotif from Kill la Kill, "Before My Body Is Dry", features one.
- Inverted with Tengen Toppa Gurren Lagann's "Libera Me From Hell", which is more of a rap song in which a wild opera singer appears (though the operatic parts get more of a focus within the show itself.)
- Inverted with the first theme of Yo-kai Watch, the "Gera Gera Po Song". It's predominantly a rap in both Japanese and English, though the English version (which retained the audio of the original OP) is more blatant in tone.
- Demetri Martin brings this trope up in his 2015 special Live (At The Time).
Demetri: I just thought that was hilarious, because you never see that in any other art form. Not like literature; y'know, you're reading a book: "What'd you think of that novel?" "Pretty good, y'know, I got into the story, first seven chapters. Then in the middle there was a really angry first-person essay... this other writer, I dunno if they're friends or something. Y'know, this guy has a big dick, he's gonna sleep with all these women, and it's a whole thing. He's not gonna buy 'em stuff, though, he made that clear. He'll sleep with them, but he's not looking to get tied down. All caps. Very confident. Lot of it rhymed, and then the essay was over and it went back to the story; y'know, it was all right."
Films — Animation
- Who could forget the rapping dog in Titanic: The Legend Goes On?
- The sequel to the other animated Titanic movie, The Legend of the Titanic, gives us a rapping shark. Yo, yo, yo! Look at my teeth!
- In a similar vein, the rapping Cheshire Cat in The Care Bears: Adventure in Wonderland.
- Nigel breaks into one in Rio 2 during his impromptu version of I Will Survive.
- The Frozen scrapped Villain Song "Cool With Me" featured a section where Elsa rapped the names of the snowmen who she was "cool" with.
Elsa: Svensen is cool with me, Jensen is cool with me. Jorgen and Fjorgen and Bjoergen are cool with me. Gunthar and Gunnar think I’m okay. Diedrich and Friedrich and Jose. And Olaf's my first one, he's kind of my worst one.
Olaf: I have a perfect physique!
Elsa: I find jobs that'll suit him and always include him and NOBODY calls him a freak.
- The ending credits to Shaun the Sheep: The Movie play over an extended version of "Life's a Treat" (the TV theme song by Vic Reeves) with additional material by the rap duo Rizzle Kicks.
- "You're Welcome" from Moana contains Maui rapping near the end. It isn't so obvious (especially since Maui sings the rest of the song too), however the version by Jordan Fisher and Lin-Manuel makes it more obvious that it's a rap.
- My Little Pony: Equestria Girls – Magical Movie Night: The "Dance Magic" music video is overall disco-themed, but is interrupted in the middle by a rap sequence from Pinkie Pie.
- Robin Williams gets a disconcertingly upbeat rap number about Animal Testing in FernGully: The Last Rainforest.
Films — Live-Action
- Sister Act 2 has some isolated instances of rapping.
- Those three rappers who make a cameo in Scenes From a Mall. ("California! The sun shines hard! People wear shorts on the bulla-vard!") They're not interrupting a musical number, but it's still pretty random.
- In Teen Witch, the main character and her friend happen upon a few street kids rapping. The main character uses her magic to give her friend the power to rap back at them.
- Tex Richman does this for his Villain Song in The Muppets. This is actually inverted in the full number, which had an opera break that was cut from the final film.
- Julien Donkey-Boy: "WELL. I'M. A. BLACK ALBINO, STRAIGHT FROM ALABAMA..."
- The page image is from the intro (and outro) to Robin Hood: Men in Tights, where the trope is very much Played for Laughs.
- Kamen Rider:
- "Climax Jump (Gun Form)" and "Climax Jump (Den-Liner Form)", two of the many versions of Kamen Rider Den-O's opening theme, both feature a random rap by Ryutaros in the middle.
- A non-bridge example is "Te wo Tsunagou" from Kamen Rider OOO which features random rapping by Ankh.
- Taken Up to 11 with Kamen Rider Ghost, which features raps as the jingles for the Eyecons.
- The Conan O'Brien parody of "Friday" had a rapper show up, utterly confused by his own role in the song.
- The German Olympic skater Katarina Witt appeared in several Christmas TV specials in the early 1990s. In one of them, out of nowhere she suddenly breaks into a full-on rap.
- Doctor Who: "The Greatest Show in the Galaxy" opens with the Ringmaster unexpectedly rapping expository dialogue: a dramatic device not used before or since in the show's entire history. Justified: the Ringmaster only does this as another way to entertain the Gods of Ragnarok between acts.
- "Kick It!" from Drew Carey's Improv-A-Ganza is a regular improv scene which switches to rap and back at another player's command.
- "Twin Bed" from the Saturday Night Live has Jimmy Fallon who was previously one of the boyfriends suddenly start rapping.
- Robin Sparkles' Let's Go to the Mall.
- Dean Learner does one on the ghastly wannabe pop hit in Garth Marenghis Darkplace.
- In Crazy Ex-Girlfriend, Rebecca sings a song called "The Sexy Getting Ready Song," which features rapper Nipsey Hussle right in the middle ... until he sees all the stuff that women use to get ready and decides that he's got to apologize to some "bitches."
- Justified by TLC, due to rapper Left Eye being part of the group. She also guest-appeared in songs by other artists. Despite being a fairly tame rapper by 90's standards, her verses still tended to be cut in radio edits.
- Mariah Carey's "Fantasy" remix attracted a ton of attention at a time where pop singers rarely collaborated with rappers. Featuring Ol' Dirty Bastard, it became just as popular as the original, and critics credit it with popularizing this trope.
- Katy Perry:
- "California Gurls" features a rap by Snoop Dogg.
- Also by Perry, a version of "E.T." (featured in the music video) had Kanye West doing a rap in it. This is especially hilarious because Kanye ruins any subtlety the song had about romance with someone extremely different from yourself, by interjecting with "Tell me what's next? Alien sex!"
- No less than four of the six singles off Perry's album Teenage Dream featured A Wild Rapper Appears. Only one, the aforementioned "California Gurlz", had the rap present on the album; for the others, the rap was added for the radio release.
- "Dark Horse" has a rap portion near the end, courtesy of The Three Six Mafia's Juicy J, who unlike Kanye deserves credit for not breaking the flow of the song.
- Lady Gaga:
- Lady Gaga featured Flo Rida on "Starstruck", a track from her debut album, The Fame. It's not a very well-known song of hers, but it's still kind of out-of-nowhere, especially considering Gaga rarely has guest verses on her songs.
- ARTPOP has "Jewels N' Drugs" which ups the ante by featuring three guest rap verses, from T.I.., Too $hort, and Twista respectively.
- "Friday", by Rebecca Black, is a well-known example of this trope, provided by producer Patrice Wilson.
- Subverted and lampshaded in Black's follow-up song "Saturday". The song itself has no rapping, but at the end of the music video a random rapper bursts into the house party spitting disjointed rhymes, and is promptly dragged off by police while the party-goers look on awkwardly.
- Justin Bieber frequently has rappers do this in his songs:
- The weirdest is "Never Say Never" with Jaden Smith, who isn't very good at it.
- "Baby" is a very popular song, and a clear-cut example if you're not familiar with the trope.
- As his appearance on a Chris Brown mixtape track, as well as his freestyle over Kanye West and Jay-Z's "Otis", prove, Justin Bieber is a pretty decent rapper himself. He never does it in his own songs though.
- Nicki Minaj pops in out of nowhere for a verse of "Beauty and a Beat." The implied date rape ("You know I'm gonna hit 'im with the ether") is a little offputting. It's highly improbable that was Nicki's intended meaning. In hip hop parlance, it's more likely to mean something more along the lines of "I'm going to do a really good job rapping." Commonly used slang in rap music (check out the song "Ether" by Nas).
- Ludacris, T-Pain, Flo Rida, Pitbull and Lil Wayne frequently enter this as they work in basically everything (the first is one of those who worked with Bieber).
- Fittingly, Ludacris has also worked with Usher; the rap segment of "Yeah!" was his doing.
- General consensus about Ludacris is that whatever song he appears in becomes better because of him showing up, and that his guest verses are much better than his actual songs.
- Increasingly this is true with Rick Ross, Mac Miller and French Montana as well.
- Kanye West, Eminem and Jay-Z have shades of this as well, but the collaborations they do like this are quite rare, and it's often much less jarring when they do so.
- Case in point for each of them - Kanye in "American Boy" by Estelle, Eminem in Akon's "Smack That", Jay-Z in "Crazy in Love" by Beyonce, although it didn't work quite as well for Jay-Z in "Lost+" by Coldplay
- It also didn't work very well with Jay-Z in "Suit and Tie" by Justin Timberlake, as the verse is very disconnected from the song and plays over a slower beat.
- Kardinal Offishall is this to the Canadian market. Of note is his appearance in Raghav's "So Much", which features a unique take on the rap bridge (specifically, Raghav himself sings the first third of the bridge and Kardinal Offishall raps the final two-thirds).
- This is practically Pitbull's Modus Operandi. Starting with Usher's "DJ Got Us Falling In Love" from 2010, there have been more songs that feature him as this trope than there are with him as the main singer (and even for those, he nearly always has someone else filling in for this trope's role, though usually by singing and not rapping.)
- Nicki Minaj is also known for this, to the point where much of the songs included in her record-breaking (beating Aretha Franklin for the woman with the most Billboard Top 100 hits) number of hits are featured verses and not her own songs. Like with Ludacris, some critics claim that her features are better than her actual songs.
- Fittingly, Ludacris has also worked with Usher; the rap segment of "Yeah!" was his doing.
- Subverted in "Rapture" by Blondie, although considered the Ur-Example. Instead of someone else rapping in her song, Debbie Harry does it herself. Even when they had Coolio appear on "No Exit", they dodged having a true example of this trope - both Debbie Harry and Coolio were rapping in the verses.
- Oddly, when Kanye West was in his Autotune-phase, "Amazing" felt very much like this, despite West being a rapper himself, after his singing for 2 and a half minutes, Young Jeezy's appearance is very jarring.
- Despite Lil Wayne at the time being the other major Autotuned rapper in the industry (although this depends on if you class T-Pain in what would be a very loose definition of the term "rapper"), his rap on "See You In My Nightmares" on the same album is as, if not more, jarring - especially since he sings the chorus on Autotune. You read that right: Two rappers (both of whom use Autotune frequently) did a song and made the rap part sound out of place.
- Jenna Rose's song "My Jeans" has a rapper named Baby Triggy show up in the middle of the song.
- R.E.M.’s "Radio Song" has KRS-One rapping at the end. Much later Q-Tip would contribute a rap verse to "The Outsiders".
- KRS also appears in the middle of Noisia and Mayhem's "Exodus". It's not everyday you hear someone rap over a Neurofunk track.
- "Underneath It All" and "Hey Baby" by No Doubt - but note that Lady Saw and Bounty Killer are Jamaican Dancehall Reggae artistes, rather than rappers.
- The "All Day, Every Day" remix of Texas's "Say What You Want", which features RZA and Method Man of the Wu-Tang Clan.
- Sonic Youth's "Kool Thing" uses this. Although instead of delivering an actual rap, Chuck D just responds to Kim Gordon's spoken monologue with deliberately vague, meaningless hip-hop cliches ("Tell it like it is... Yeah, word up!")
- Hard 'n' Phirm's "Pi" features fellow comedian/musician Howard Kremer aka Dragon Boy Suede.
- Kevin Max's "Existence" has a bridge featuring Knowdaverbs from GRITS.
- 'Alligator Sky' by Owl City.
- Three versions of the song exist, the original version with Shawn Christopher, one without any rapping, and another rap version with B.O.B. that hasn't been officially released and came about from a friendly back and forth between B.O.B. and Adam Young on Twitter.
- Live show version: Instead of playing the song without the rap portion, the album version of the rap is played...with Shawn Christopher appearing through a prerecorded projection, similar to the kind used for Vocaloid live shows.
- UB40's cover of "Red Red Wine" has in some versions a Reggae-Rap section. Neil Diamond's original version is unsurprisingly absent of rapping.
- A much earlier example: "Every Little Step" by Bobby Brown has a rap portion, though by Bobby himself.
- Sam Smith's "I'm Not The Only One" has a remix featuring A$ap Rocky, who sings the intro and bridge of the song.
- Emilie Autumn, of all people, does this in "Opheliac". It's done by Emilie herself, though.
- Kevin Rudolf has this in many of his songs, but it's justified due to him being signed to Cash Money Records and actually associating with the guest rappers on a regular basis. It doesn't make their appearances any less sudden, like with Lil Wayne on "Let It Rock" and Rick Ross on "Welcome to the World". Often the lyrics of the rapping don't have any association with the rest of the song.
- Parodied by inversion in "Jack Sparrow" by The Lonely Island, where a rap song has a wild Michael Bolton appear...
- Also parodied in YOLO, where their song is interrupted by Kendrick Lamar's rap... about investment and retirement advice. It's actually sound advice. In fact, their rap is interrupted by Adam Levine's singing, whereas Lamar's rap fits the group's music genre. So it's more an inversion, Suddenly A Wild Singer Appears.
- "Electronic Pleasure" by N-Trance.
- "Good Kill" by Too Much Joy ends with a rap by KRS-One. Oddly enough, this was released the same year he also appeared on R.E.M.'s "Radio Song".
- Bad Religion's "Let Them Eat War" features a rap verse by Sage Francis.
- Parodied on the song "Pop Song" by Jon Lajoie
And now the token rap verse that doesn't make any senseBut helps me get a small percentage of the urban music market
- "Lost+" by Coldplay, courtesy of Jay-Z.
- Pete Townshend's "Who Are You (Gateway Remix)", which is basically his solo version of The Who song, includes a rap verse by Hame.
- Inverted in the Eminem song "Stan", which features refrains from pop singer Dido. The song helped get Dido's own single out.
- Also inverted with The Black Eyed Peas song "Where is the Love?", which has Justin Timberlake singing the refains.
- The now little-remembered Charity Motivation Song "Voices That Care" included a brief rap by Will Smith. This was even more jarringly, awkwardly done in the Dutch answer to this, “Als je iets kan doen” by Artiesten voor Azië.
- "My Love" by Justin Timberlake features an appearance by T.I.
- The 2010 Haiti remake of "We Are the World" has a whole section of this.
- Parodied by The Axis of Awesome in their How To Write A Love Song where Lee pops in with a rap in the middle of their R&B love song.
- "Roll the Bones" by Rush, provided by usual vocalist Geddy Lee, but with his voice drastically altered via studio effects.
- Madonna's "Give Me All Your Luvin'" kind of doubles up on this - the bridge has both M.I.A. and Nicki Minaj rapping for a few lines each.
- Michael Jackson thought that rap wouldn't catch on, according to Quincy Jones, back in The '80s. Once he was proven wrong, wild rappers became a mainstay on his albums.
- "Black Or White" (Dangerous) has a rap bridge credited to a mysterious "L.T.B." note . The video has Macaulay Culkin lip-sync this part.
- "This Time Around" (HIStory) and "Unbreakable" (Invincible) both feature The Notorious B.I.G.
- "2 Bad" (HIStory) features Shaquille O'Neal.
- "Heartbreaker" and "Invincible" (Invincible) feature Fats.
- The entirety of the 25th anniversary re-recording of Thriller has them.
- "Jam" (Dangerous) features a rap by Heavy D.
- Speaking of Heavy D., His Royal Heaviness also interrupts a remix version of Michael's sister Janet Jackson 's song "Alright" to lay down a few lines as well.
- "Rollin' (The Ballad of Big & Rich)" by Big & Rich has a guest appearance by Cowboy Troy in the middle.
- Kirsty MacColl's "Walking Down Madison" has a rap bridge by Aniff Cousins. He doesn't entirely appear out of nowhere though - he also gets the spoken line "would you like to see some more?" in the chorus.
- The Jessie J song "Price Tag" has a rap by B.o.B.
- And then there's the Dizzee Rascal and Big Sean raps in Jessie J's "Wild" which don't fit the style or the content of the rest of the song. Dizee even takes over mid-verse.
- The last verse of Riskay's positively delightful "Smell Yo Dick."
- Wiz Khalifa:
- Maroon 5 has Wiz Khalifa appear in "Payphone."
- Khalifa also appears in Cee Lo Green's "Bright Lights, Bigger City". It should be noted that the studio versions of both songs omit Khalifa.
- Interestingly, one of Khalifa's own songs features this. "See You Again feat. Charlie Puth" begins with a somber piano and vocals by Puth, before having multiple sections where Khalifa raps. The disconnect is strong enough that there's a version that omits Khalifa entirely that gets ample radio play (mainly on adult contemporary stations).
- Betty Wright And The Roots' Betty Wright: The Movie has three such appearances - Snoop Dogg on "Real Woman", Lil Wayne on "Grapes On A Vine" note and Robert "The Messenger" Bozeman on "Hollywould". Though The Roots are a hip-hop group, they only provide instrumentation on the album, and most of the vocals are sung by Betty Wright herself.
- Three tracks on Giulietta's debut album Ascension featured an uncredited MC. Her sophomore album/mixtape, 911: Code Pink, featured no less than seven rappers, all credited.
- Daisy Dares You's sole hit, "Number One Enemy", features Chipmunk, whose appearance is one Big-Lipped Alligator Moment within the song.
- "You're Freaking Me Out Girl" by Wired All Wrong has a rap bridge provided by Count Bass D. He was most likely brought in due to connections with Wired All Wrong's vocalist Matt Mahaffey - both hail from Tennessee, and Count Bass D was once signed to Spongebath, the independent label Mahaffey co-founded.
- Not quite a rap break, but the Anthrax song 1000 Points of Hate features dj scratching by Public Enemy's Terminator X.
- Disney Channel examples:
- "Tell Me Something I Don't Know" by Selena Gomez features one by an uncredited rapper.
- "Intuition" features raps by Eric Bellinger.
- "Who's That Boy" by Demi Lovato features a rap by Dev. (However, since they almost sound similar, it's hard to tell if Demi or Dev was doing the rap in the middle of the song.)
- "Liberty Walk" by Miley Cyrus, rapped by Miley herself.
- "Tell Me Something I Don't Know" by Selena Gomez features one by an uncredited rapper.
- The cartoon themed group Gorillaz is an interesting case. Their first hit single - called "Clint Eastwood" - featured Del The Funky Homosapien as the rapper. From there on, quite a bit of their singles have been examples of this. Album-wise they do include various vocal collaborators, but most either carry the entire song (except, perhaps, for a chorus by 2D) or aren't rappers at all.
- Islands' "Where There's A Will There's A Whalebone" is sort of unusual, as it technically features more rapping than singing, yet still feels like an example of this: usual vocalist Nick Thorburn sings in the beginning and end of the song, but the whole middle section is ceded to guest rappers Subtitle and Busdriver.
- All I Need Is Love by Cee Lo Green and The Muppets has a rap bridge... performed by Pepe the King Prawn.
- Reggae song "Informer" by Snow features producer M.C. Shan jumping in to rap for a bit.
- Madcon's cover of "Beggin'" by Frankie Valli and the Four Seasons. Just when you think it could be a worthy cover of a classic song, a random rapper appears. Fans of the original weren't happy — at all!
- Bruce Springsteen has this happen on the song "Rocky Ground" from his album Wrecking Ball features background vocalist Michelle Moore rapping the song's final verse.
- The Jonas Brothers song "Burnin Up" features a rap by the brothers' bodyguard Big Rob.
- The Brad Paisley song "Accidental Racist" features LL Cool J doing one of the strangest rapping bits of all time.
- Ariana Grande:
- A very early version (possibly the ur-example, and definitely an awesome example) was the Run-DMC cover of Aerosmith's "Walk This Way" in which the rappers took over the vocals.
- Gersberms by Hard 'n' Phirm (a song based off the Ermahgerd meme) has a rapping bridge from The Swedish Chef of all things.
- Averted with everything from rock band Zebrahead, for which rapper Ali Tabatabaee is actually one of the two vocalists in the band and his rapping is just part of their style.
- Enter Shikari do this in too many cases to count. Interestingly, the rapping is always done by lead singer Rou Reynolds.
- Same with Thousand Foot Krutch, enough that they can be considered Rap Rock. Their lead singer, Trevor McNevan, also inverts this in his relationship with Christian rapper Manafest. McNevan discovered Manafest and helped promote him as an artist, and as such he makes a guest appearance at least once on most of Manafest's albums. It has yet to be reciprocated, though, most likely due to the aforementioned Rap Rock.
- Cash Cash:
- Alice Cooper's "Dirty Diamonds" album was his usual style, right until Xzibit shows up for the bonus track at the end. The guest appearance was a little less inexplicable when "Stand" first appeared on Unity: The Official Athens 2004 Olympic Games Album a year earlier, since it was a compilation themed around collaborations.
- Pet Shop Boys' "Thursday" is a disco/house song, with Example rapping over the bridge.
- 30 Seconds to Mars "Hurricane" is a rock song with rapping by Kanye West in it. There's a version without it and an extra chorus replacing his portion though; that version tends to be the preferred, especially by fans of the band.
- Vitamin C's hit "single", Smile was actually more of a duet between her singing and Lady Saw's rapping.
- Outkast's "Roses" features a rap verse by Big Boi. Normally this wouldn't really be an example because Outkast are Andre 3000 and Big Boi as a hip hop/soul duo. However, "Roses" is otherwise entirely sung by Andre 3000, and the Distinct Double Album format of Speakerboxxx/The Love Below means that this is one of the few times on either disc that both members appear in the same song.
- "Runaway" by Cabaret Voltaire, from an album that's essentially house meets Synth-Pop, contains a rap segment fitting in with the song's theme of money.
- Amy Winehouse's "You Know I'm No Good" has two remixes featuring Ghostface Killah: One restructures it as Call-and-Response Song, with each of Amy's sung verses receiving a rapped response from Ghostface. The other is a straighter example, since it's a shortened version of that same remix where Ghostface only gets one verse near the end of the song.
- Linkin Park is quite fond of this trope, using it on their remixes, along with Rakim in their single "Guilty All the Same". Of course, like TLC above, they also have a rapper as a member of the band with Mike Shinoda, making it a Justified Trope when a song features rapping.
- In what's probably the only example of this trope (so far) occurring in a Symphonic Metal song, Within Temptation's "And We Run" features a rap bridge by Xzibit. This actually caught the band some flak before the release of Hydra ("Pimp My Metal" jokes were fairly common for a while), although that subsided once the album came out and people finally listened to the actual song.
- Peter Hollen's version of Queen's "Don't Stop Me Now" features a rapid-fire rap by George Watsky.
- "Jesus Freak" by dc Talk. Subverted in that although it's a rock song, dc Talk was predominately a hip-hop group in their early days.
- The Music/Doubleclicks' song "Tabletop Games" features a rap verse by Adam WarRock.
- "Cruise" by Florida Georgia Line got a remix that featured Nelly, which actually propelled the song to even more popularity, making it to the top 5 and going 8x platinum. Nelly's verse tends to get removed on pop radio, which its as ridiculous as it sounds; they aired the rap remix and then removed the rap from the remix.
- LL Cool J had a wild guitarist appear in the midst of his rap ballad. The single still flopped.
- KMFDM, of all bands, does this in a few tracks on UAIOE (most notably "Murder"), courtesy of a mysterious Jamaican vocalist by the name of Morgan Adjei. Suffice to say, it isn't one of their more popular albums.
- Strangely, "Tokyo Tower" by Japanese disco/funk artist Toshiki Kadomatsu not only features, but opens up with an English rap by an unnamed rapper. Even more strangely, it actually seems to be relevant to what the song is about.
- The otherwise retro-electronic album "Outrun" by Kavinsky has a rap song ("Suburbia") with lyrics by Havoc appear out of the blue before resuming the retro-electronic beat. It's doubly out of place when it refers to Twitter, which didn't become popular til long after the album's story takes place (1986 and 2006).
- Celia Cruz's "La Negra Tiene Tumbao" has random sections sprinkled in it, especially roughly 3 minutes in.
- The soundtrack of The Hunger Games: Mockingjay Part 1 is mostly electronica/pop with primarily female artists, with the exception of the opening track "Meltdown". The song features Q-Tip and Pusha T rapping verses while the soundtrack curator Lorde sings the chorus. No other song afterwards features any rapping.
- This has become a much more common thing in Christian Rock, following the rise of Lecrae and the Christian Rap genre in general. Chris Tomlin, Britt Nicole, and Jimmy Needham, among others, have brought in Christian rappers to add youth appeal to their more traditional style of CCM.
- Inverted with equal frequency, as Christian rappers bring in non-rap artists to appear on their tracks. This has led to unorthodox pairings such as Lecrae and Tenth Avenue North, NF and Britt Nicole, and Andy Mineo and Mac Powell (lead singer of Third Day).
- Was zig-zagged all over the place during the finale of each show on the Summer Shed Tour, which featured tobyMac, Skillet, and Lecrae. Being a former member of dc Talk, Toby was able to perform Jesus Freak (as mentioned above) as the encore of his set (which finished the show). But in addition to the existing rap bit, he brought out both Skillet and Lecrae to help. Lecrae (and labelmate Tedashii, who was headlining for him) added an additional rap verse to showcase their own abilities, and Skillet contributed their own musical style, turning one of the cornerstone songs of modern Christian Rock into an epic metal-rap fusion in the name of Jesus.
- "Hanging On" by Ellie Goulding is a very somber, subdued song. In an infamous remix of the song, it's interrupted in the middle by a random rap segment by Tinie Tempah involving some rather crude lyrics that don't fit with the song at all, resulting in what may possibly be the biggest case of Mood Whiplash in music history. To say that fans of the original song loathe this particular version would be putting it very mildly.
- On MilkCan's Make It Sweet!, PaRappa the Rapper shows up in the second half of "GOT TO MOVE! (Millennium Girl)", mostly mirroring the lyrics that Katy is singing.
- Rap Rock band Hollywood Undead features rapping in most of their songs, rarely are there guest vocals. However, something to this effect was done in "Believe". It's sung mostly by Danny, the bands singer, until halfway through where there's a rap by Johnny 3 Tears. Then at the end, J-Dog jumps in for a rap, before the song finishes.
- The Ur-Example could very well be Paul Simon's music video for "Me and Julio Down by the Schoolyard," which is introduced by a rapper and a beatboxer.
- The Weeknd's song "The Hills" received an official remix featuring Eminem, which replaces the two original verses with two guest rap verses. It was actually well-received.
- K-pop loves this trope to the point where nearly every song has a rap break and every group has a designated rapper included in the lineup.
- Ed Sheeran's "Don't" has a remix with rapper Rick Ross. It's also the only version where you can hear Ed sing 'fuck' uncensored.
- El Sol Caracol's first (and so far only album) is composed mainly of various Latin (particularly Caribbean) infused varieties of pop and rock. The second song, "El Compa", contains a rap interlude.
- Inverted on the version of "Ghostbusters" from Ghostbusters (2016) by Fall Out Boy and Missy Elliott - Missy does just about all the vocals on the track with Patrick Stump doing occasional sung lines on the chorus.
- Sting got in on this on the album Brand New Day. While the chanting on 'Desert Rose' makes some sense, why is French rapper Sté Strausz breaking in on 'Perfect Love ... Gone Wrong'?
- Sugar Ray's "Fly" features Super Cat, another example of a reggae artist in this role. In fact, one version of the song features Super Cat doing an entire verse between the second and third verses (along with a rendition of the nursery rhyme Georgie Porgie, near the end of the song).
- Grace's cover of "You Don't Own Me" by Lesley Gore adds a rap portion by G-Eazy. The rap portion is a love it or hate it deal, especially by those who enjoy the original (which are a minority, at least with younger fans).
- The Steeleye Span album Dodgy Bastards has a version of Steeleye standard "Boys of Bedlam" with a rap section written by Alex Kemp (son of Maddy Prior and Rick Kemp). On the album it's more of a spoken-word section performed by Julian Littman, but the liner notes say there's a full-on rap version performed by Alex (and with more explicit lyrics). There's a similar section in "Bad Bones" on the same album, this one written by Littman.
- Played for laughs in the song "Every Bollywood Party Song":
Every song has an obligatory rap portion
Sing in a rustic accent for a regional collection
- Erasure's cover of "Take a Chance on Me" (originally ABBA) has a bridge full of MC Kinky reinterpreting the song as unintelligible raggamuffin toasting. MC Kinky, incidentally, is just as white as Erasure and ABBA, and she grew up in London, not Jamaica.
- By A Cappella group Pentatonix, in the single version of Can't Sleep Love, Tink jumps into the bridge of the song to rap for a couple of seconds, before disappearing again.
- The single "World in Motion" by New Order, made for England's 1990 FIFA World Cup bid, has a cringe-inducing rap bridge performed by England footballer John Barnes. It's quite something to behold.
- General Public's cover of I'll Take You There (originally by The Staple Singers) features another reggae example, with Ranking Roger doing an original reggae / dancehall verse that doesn't appear in the original version.
- The Neighbourhood's "#icanteven" contains a rap section by French Montana. It seems to be from the POV of the person that the singer's girlfriend cheated with.
- The Aquabats!:
- The bridge for "Pool Party!" features MC Bat Commander doing a rap verse.
- "Radio Down!" features a rap verse with Word Salad Lyrics by Biz Markie.
Pump the bass, pump it to highs
I want some ketchup with my hamburger and fries
You know me as B-I-Z M-A-R-K-I-with an-E
And this is how I slow it down in the place to be
Ooh, ah, I want a piece of pie
No matter what I say, it always comes out fly
That why I'm with the brothers that's got it like that
They go by the name of The Aquabats!
- In Pokémon Live!, Giovanni's otherwise serious Villain Song has a part where Jessie and James recite their motto by rapping.
- The short-lived and critically panned hip-hop "street cat" version of Rum Tum Tugger in Andrew Lloyd Webber's Cats performed his song as a rap. There is no rapping anywhere else in the musical, and so his number (and frankly, the new version of the character as a whole) seems out-of-place. That's why "street cat" Tugger was eventually phased out in favour of the original rock star.
- His World from Sonic the Hedgehog (2006) might shock you with this once you reach the credits, since its melody is teased throughout the game, but you never get any indication that a rap is coming.
- The album version of Kanon (2006)'s ending theme has a random and incomprehensible rap segment. No, really. What's more, it was prominently featured in the show's trailer
- The first boss theme for Einhänder, surprisingly an Ear Worm. This rap was justified by being a sample from a then-famous disc, Masterbits Climax 9 - RAPsody (Vocals II).
- The Final Fight stage theme in the arcade version of Capcom vs. SNK: Millennium Fight 2000 has a gangster rap segment, complete with profanity. The console ports of the game cut out the rap segment.
- The intro to Brütal Legend features a rap segment in the middle of a metal song. Right after the pop segment. Don't worry, they all die before the game starts proper.
- U.S. Tuned, the North American opening for Auto Modellista.
- The normal battle theme for Ar tonelico: Melody of Elemia has a random rapper enter the song just before it loops.
- Off the Hook from Splatoon 2 is a music duo consisting of pop vocals by Marina and rap vocals by Pearl, all done in Conlang.
- The credits theme of Monster Seeking Monster from The Jackbox Party Pack 4 contains a rap segment about a minute and thirty seconds in.
- Homestar Runner: Inverted with "Rap Song" by Coach Z (accidentally) featuring Peacey P. The song itself is all rap, but has an R&B break, performed by Tenerence Love. "Loading Screens" is a straight example, as is "Trudgemank".
- "In the Ocean Blue", from the third episode of Charlie the Unicorn, is occasionally interrupted by a shrimp rapping names of many sea creatures similarly to the Pokerap.
- In the album version of Yang Xiao Long's Leitmotif "I Burn", Lamar Hall suddenly breaks in with a rap verse.
- Lamar Hall again makes a rap appearance in Team CFVY's theme "Caffeine", though it makes more sense there given how fast the rest of the song is sung.
- The Newgrounds music videos of "Beware the Forest's Mushrooms" from Super Mario RPG, "Rawest Forest" and "Waltz of the Forest," both have rap verses.
- "Do You Wanna Date My Avatar?" by Felicia Day has a wild rap verse performed by Jeff Lewis (Vork) and Sandeep Parikh (Zaboo).
- TomSka's "Shoot All Your Problems Away"—a light and upbeat little song—has the man himself appear to give a short rap.
- Lampshaded and discussed in the Key of Awesome parody of Katy Perry's "ET":
Katy Perry: Kanye,/Why are you here?/I don't like this version./You're not on the album.
Kanye West: Katy, ungh,/Let me be clear, ungh./Every single pop hit/Needs a rapper on it.
- Todd in the Shadows:
- Todd said that he checked out Justin Bieber's new Christmas album because a live version of a song had one featuring Busta Rhymes.
- While many of the songs he has reviewed include the trope, his review of "Girl On Fire" by Alicia Keys parodies it with random momentum-destroying appearances by The Rap Critic to talk about Nicki Minaj's added verses.
Todd: All this song is is a creatively exhaustive, meaningless pile of—
Rap Critic: And then the featured guest randomly comes back in, ruining the momentum of the video!
- This video from Chester See and Tobuscus features Wayne Brady as the wild rapper.
- Party of Three by the band NinjaSexParty features a subversion of this trope when Arin "Egoraptor" Hanson starts rapping at a pool party... Only to come back moments later with the lead singer, Danny "Sexbang" Avidan rapping himself.
- This gets parodied mercilessly in the Yogscast song "Does Santa Claus", which is a parody of charity movements such as "Do They Know It's Christmas". After it alternates through various members of the Yogscast, Hat Films come and do an impromptu rap which completely clashes with the rest of the song, then disappear again. Just before the song rounds up, In The Little Wood does the same thing.
- The Jacksfilms song "Take Off Your Clothes (Like Scarlett Johansson)" features Toby Turner, aka Tobuscus, appear to deliver a short rap, then skateboard away.
- The SCP Foundation has SCP-2137, "The Forensic Ghost of Tupac Shakur" (written by Max Landis), where long-unsolved crimes by still active criminals would be told in a song by an old artist (including the Andrews Sisters, Frank Sinatra, and The Who) featuring a guest verse by Tupac Shakur (who is normally the "primary artist", doing a rap about a murderer on the loose).
- Just like in the Payphone example above, Siiva's "Snow Halation (Demo)" (a mashup of "Snow Halation" and "Payphone") features Wiz Khalifa showing up to rap during the solo.
- "Go My Way!! (REM@STER-A)" (another mashup of "Snow Halation", this time with "Go My Way!!") randomly features DMX rapping for the last measures of the 1st chorus. (This is a reference to an old mashup of Go My Way!! with Where the Hood At.)
- Exaggerated in the Phineas and Ferb episode "Spa Day", which has a song with relaxing, lounge music, except for a completely out-of-the-blue rap tune interrupting it in the middle - the catch being that the rap section made up the majority of the song.
- Rick and Morty: Parodied in the episode "Total Rickall," where Summer is taken on a magical My Little Pony-style fantasy musical sequence that gets jarringly interrupted by a rapper who shouts angry rap verses out of his sports car.
- Total Drama World Tour: Harold interrupts some songs to start rapping, much to the others' annoyance. Gwen also does it during the song "Gypsy Rap".
- The VeggieTales song "BellyButton".
- The opening theme to Liberty's Kids, with a rap courtesy of Aaron Carter:
I take my heart into battle
Give that freedom bell a rattle
Gonna have independence signed
I'll sign right here on the dotted line
Red, white, and blue, never give up
We represent America!
- Schoolhouse Rock has one in the form of a rapping walrus during the solo parts of the otherwise rock & roll-themed "Save the Ocean" in "Earth Rock", provided by Eric "Badlands" Booker.
- In one of their tie-in music videos, The Simpsons did an in-universe one, with Bart interrupting a school recital to perform "Do the Bartman." (Amusingly, this would be referenced in a Call-Back on the TV show proper about a decade later, with a character, no other than Ralph Wiggum, mocking it by saying "That is so 1991!")
- In the Littlest Pet Shop (2012) episode "What, Meme Worry?", the Biskit twins have their butler LeGrande do this in their music video.
- This promo for The Amazing World of Gumball has Richard as the rapper.
- How Murray Saved Christmas: The Easter Bunny does this during the town's anthem number.

- Parodied in one episode of Kaeloo where Stumpy dresses up as a rapper and starts rapping for no reason... in the middle of a basketball game.
