[[folder:Opening & Ending Themes]]
We could easily say ''every single opening and every single ending from both animes''. Yes, they are ''that'' good. But if we get specific:
* From [[Anime/FullmetalAlchemist the 2003 series]]:
** The very first opening to the 2003 series, [[http://soundcloud.com/lojageekmania/full-metal-alchemist-melissa "Melissa"]].
** [[http://www.youtube.com/watch?v=dd1V816mVdU "READY STEADY GO"]], the first and main song Creator/AdultSwim used throughout most of its run, and the second opening overall. Zebrahead's [[http://www.youtube.com/watch?v=dd4zl9cX02A English-language cover]] is pretty intense, too.
** COOL JOKE's [[http://www.youtube.com/watch?v=gIkYDNbtYxg "Undo"]] as the 3rd opening is pretty amazing. It's pretty catchy, and it also fits the Elrics to a T.
** Opening 4: Music/AsianKungFuGeneration's [[http://www.youtube.com/watch?v=ZmeudwRMrsU "Rewrite"]]. One of the best-known songs from the anime. Darling Thieves' [[http://www.youtube.com/watch?v=SxUkj1dvd24 cover]] of it is a whole different flavor.
** The first ending theme song, [[http://www.youtube.com/watch?v=B78VeNU_RWA "Kesenai Tsumi"]].
** [[http://www.youtube.com/watch?v=wZVcyp5q-ds "Tobira no Mukou e"]], the second ending. It's especially wonderful if you look up the lyrics.
** Crystal Kay's [[http://www.youtube.com/watch?v=TxYJGX7y0Ts "Motherland"]], the third ending theme, is very touching.
** The fourth ending, [[http://www.youtube.com/watch?v=07DqhnVX-QY "I Will"]], is strangely catchy.
** [[http://www.youtube.com/watch?v=w7ueRIJG6oo "Link"]] and [[http://musicinanime.tumblr.com/post/34121351923/lost-heaven-larc-en-ciel-anime-fullmetal "LOST HEAVEN"]], the opening and ending themes to the ''Conqueror of Shamballa'' movie.
* From ''[[Manga/FullmetalAlchemist Brotherhood]]'':
** The first opening theme [[http://www.youtube.com/watch?v=VEaPDdhPsWE "again"]], which, like "Brothers", is both heart-wrenching and beautiful.
** [[http://musicinanime.tumblr.com/post/67421288681/hologram-nico-touches-the-walls-anime "Hologram"]], the second opening, is normally really good, but being reused for the ending photo montage was possibly the best way imaginable to bring the series to a close.
** It may not be as epic as some of the other opening themes, but [[http://www.youtube.com/watch?v=0iAF8TJAqp4 "Golden Time Lover"]], the third opening, makes up for it through sheer [[EarWorm catchiness.]]
** CHEMISTRY gets music of awesome with [[http://www.youtube.com/watch?v=9vx69Pe7Ncs "Period"]], the fourth opening. This is the best way to start an episode.
** The 5th Opening [[http://www.youtube.com/watch?v=1YNViujuP4Y "Rain"]] by SID is too beautiful for words. The [[http://www.youtube.com/watch?v=s8GIo_YDHkU MIDI version]] is also incredibly awesome, with the MIDI doubling as Heartwarming Music, especially if you consider the meaning behind the lyrics. Special mention should probably go to the use of it in Episode 61 of ''Brotherhood''. The episode begins with it conspicuously absent; fitting, since this is the equivalent of [[DarkestHour Chapter 104]]. [[spoiler:Everyone is "dead" and Father appears to have won]]. It doesn't play until [[spoiler:Hohenheim's circle activates that reverses the whole thing, returning everyone to life]], and that song playing over the scene just about doubles the already-high levels of [[SugarWiki/MomentOfAwesome awesome]] and [[SugarWiki/HeartwarmingMoments heartwarming]]. The use of the 5th Opening at the end of Episode 63 is incredibly satisfying as a SugarWiki/{{Heartwarming Moment|s}} AND one of the biggest {{Tear Jerker}}s of all time...
** [[http://www.youtube.com/watch?v=LbZXvmXvNQQ "Uso"]], the first ending to ''Brotherhood'' is both catchy and touching.
** The second ending song of Brotherhood, [[http://soundcloud.com/kuroyukihime-san/fullmetal-alchemist-2-let-it "LET IT OUT"]], is beautiful on it own, but when paired with the ending scenes... Moment Of Awesome/Heartwarming.
** The third ending theme, [[http://soundcloud.com/little-fox-1/tsunaida-te-lil-b "Tsunaida Te"]], is quite uplifting.
** [[http://www.youtube.com/watch?v=HEkerSi5Fig "Shunkan Sentimental"]]. The first few chords, combined with whatever epic event ended the episode...
** [[http://www.youtube.com/watch?v=ETbEtbE28VA "RAY OF LIGHT"]], the 5th ending theme to Brotherhood.
** The theme songs of the ''Brotherhood'' movie, ''The Sacred Star of Milos'': [[https://soundcloud.com/bluephantom1/miwa-chasing-hearts "Chasing hearts"]] and [[http://www.youtube.com/watch?v=u1fRy346838 "GOOD LUCK MY WAY"]].

[[AC: 2003 Series]]
* Michiru Oshima's score for the 2003 anime is regularly mentioned by anime critics as among the finest anime [=OSTs=]. [[http://www.animenewsnetwork.com/feature/2016-05-11/manga-vs-anime-fullmetal-alchemist/.101947 This article]] by AnimeNewsNetwork mentions it as one of the major reasons to watch the 2003 anime (and it's worth noting the author is a scholar of film music).
* From the very first episode, we have [[http://www.youtube.com/watch?v=--H1SdoFFis Way Back.]]
* The 2003 score features many awesome pieces. [[http://www.youtube.com/watch?v=18_epz3QDYU Amestris]], [[http://www.youtube.com/watch?v=ZPzMTfeXJnk Daring Fight]], [[http://www.youtube.com/watch?v=FMAA6VP-ces Shinryakul]], and [[http://www.youtube.com/watch?v=nVYjja-uyRM Seiatsu]] are just a few examples not mention elsewhere.
* [[http://www.youtube.com/watch?v=BOfvxkwnSs8 Beaming Sunlight]] is what you email your grandmother when she's telling you all anime is porn.
* The song "Brothers" is heart wrenching and beautiful at the same time. [[http://www.youtube.com/watch?v=IgZbd1f4x98 How can I repay you brother of mine, how can I expect you to forgive...]] Yes, that ''is'' Ed's voice actor singing and playing piano. Actually, the song after that (Nothing I Won't Give) is meant to be an original ImageSong for Ed, and it's quite badass.
* "Brothers" or "Bratja" has many versions of through the series. The [[https://www.youtube.com/watch?v=u_ddTqnOVhU&list=PL9CD1A1D6FAA8370C&index=2&ab_channel=entrevide5 harp and violin version]] is really heart-rending for me. It alone is considered one of the finest pieces of music ever written for an anime.
* "[[http://www.youtube.com/watch?v=wq5lClW_M0M Aishou]]", Lust's theme. It's used in many ways in her focus episode, "Reunion for the Fallen," where she feels conflicted about her feelings about Lujon, the man she misled to help create a Philosopher's Stone who ended up falling in love with her. There's a scene where the scalar piano parts coincide with Lust's hair blowing in the wind as she spots Lujon that is just heart-stopping on a rewatch.
* Dante's leitmotif from the first series, "[[http://www.youtube.com/watch?v=VLp_wePNrZA Dante]]."
** Or the [[http://www.youtube.com/watch?v=4tEj6gXA_eA waltz version]] used once near the end.
** The version with singing in it makes it sound like she's pleading for Hohenheim.
* [[http://www.youtube.com/watch?v=VyDlhODQpzg "Koukai"]] is easily one of the saddest tracks in the first anime. It's especially devastating when it's used in episode 15, where Ed and Al learn about the Ishbal massacre, and in various scenes that show Roy Mustang's actions during the massacre. Especially the flashback he has in episode 13 when Ed in the battle reminds him of killing an Ishbalan child, or Marcoh recalling Roy's [[spoiler: suicide attempt]] after [[spoiler: killing the Rockbells]]. Roy is a man traumatized by his regrets, and this music emphasizes that and adds to the sadness.
* Whenever [[http://www.youtube.com/watch?v=ULL9TSUfeiw Tsumi]] plays, you can be sure that something either awesome and awful (or both) is going down.
** Same with [[http://www.youtube.com/watch?v=NMASK4SdSXA Gaika]]. Special points for its first appearance in the second episode: "You're not the only one who can't stand doubters preach. HERE'S THE REAL HAMMER OF GOD!"
* [[http://www.youtube.com/watch?v=nv3aUOH635I Homunculus]], as well as its thematic reiterations (like Romei).
* [[http://www.youtube.com/watch?v=MNy0oE1AFmo "Trance to Homunculus"]], an absolutely epic VillainSong for the Homunculi of the 2003 anime, even if the "lyrics" are just quotes by the Homunculi from the show.
* The track appropriately titled [[https://www.youtube.com/watch?v=jsNRdZ-lUB0 Philosopher's Stone]] is a haunting, mysterious piece, full of airy percussion, that's perfect for the scenes with revelations about alchemy, the homunculi and, of course, the Stone.
* A lot of the big brassy songs used for scenes involving the military. [[https://www.youtube.com/watch?v=oJWlqDisISE Fortify]] is used in a lot of battle scenes, and in revelations about the military's crimes, and make it clear just how powerful it is. [[http://www.youtube.com/watch?v=UqBIQP5MjP4 "Invasion"]] also accompanies a lot of those scenes, but also some lighterhearted moments at Military HQ, which fits with how its mood is more ambiguous than the mightier, and angrier, "Fortify".
* [[https://www.youtube.com/watch?v=GowvJQvOcTA "Kei,"]] or "Devotion," which is used for a lot of the scenes in and about Ishbal, especially the ones involving Scar. The hymn-like sound to it represents Scar's devotion to his religion and his mission of revenge, and makes the whole thing feel very epic. Especially in the anime, which often omits the organ and just uses the choral track a cappella, which sounds very old and haunting.
* [[http://www.youtube.com/watch?v=fimWQ5HRzyo Greed]] gets an epic brassy theme that sounds like something from Mussorgsky.
* The use of Chopin's "Tristesse" Etude in the series finale. It's a really common choice in anime (used, among other places, in the finale of ''{{Anime/Baccano}}'' and several scenes in ''Anime/YourLieInApril''), but it's particularly well-placed here, especially given the title of the piece (French for "sadness") contrasted with its hopeful mood. It perfectly fits the bittersweet ending, [[spoiler: where the brothers are separated but hopeful and fighting for their reunion, Roy and Riza are closer than ever even after he was seriously wounded in his attempt to overthrow the Führer, and so on]].

[[AC:Brotherhood]]
* [[http://www.youtube.com/watch?v=oSs9H1ANmL4 Mortal Sin]] (played the first time Ed meets Lust and Envy).
* [[http://www.youtube.com/watch?v=l2kwie-gs2o Trisha's Lullaby]] (used to great effect when Ed and Al mourn for [[spoiler:Nina]]).
* [[http://www.youtube.com/watch?v=dJk4T0OK5RM Next Chapter]]. Note that the name is rather misleading; with a name like that you'd expect it to be something that plays during the end of an episode. Which it is--a couple of times out of 64 episodes, and only in part. More significantly, though, it is the piece used [[spoiler: when Mustang reveals his plan to fake Maria's death, and again when Wrath makes his grand re-entrance back in Central]].
* [[http://www.youtube.com/watch?v=Q_439qLQzHs Lapis Philosophorum]] (heard in the first episode).
* [[http://www.youtube.com/watch?v=Stzofz4yMSY Xing Symphony -Overture]], the theme for Xingese characters.
* [[http://www.youtube.com/watch?v=hdp_g-RYjQI To Be King]].
* The [[SugarWiki/MomentOfAwesome awesome]] theme which kicks off the battle between Mustang and [[spoiler:Envy]], [[http://www.youtube.com/watch?v=_scbziJUEog The Intrepid]].
* [[http://www.youtube.com/watch?v=QOiG4A2Vkp4 Versus Homunculus]], and its remake [[http://www.youtube.com/watch?v=8KEcpz0IE3M Knives and Shadows]]. The sound of blades clashing behind the music on the second one makes it, as does the images it conjures of the CMOA when it plays.
* [[http://www.youtube.com/watch?v=gweNNwVMClw Pride]] is also an excellent theme.
* Major Armstrong's theme, also known as [[http://www.youtube.com/watch?v=U6QqZfvE3Fw Amestris Military March]]. "COURAGE INCREASED BY ONE HUNDRED FOLD! MUSCLES INCREASED TO ONE THOUSAND FOLD!"
* [[http://www.youtube.com/watch?v=AEiucbbXBUA Requiem for the Brigadier General]] (referring to [[spoiler:Hughes]])
--> '''Youtube Reviewer:''' "Mommy.. why... why are they putting dirt on Daddy? Daddy said he has lots of work to do!" [[TearJerker I. BROKE.]]
* The [[http://www.youtube.com/watch?v=SkNjCfMjRXA Main Theme]].
* [[http://www.youtube.com/watch?v=n49L3RgGrpI Dissident's Creed]], the music when [[spoiler: Winry finds out that Scar killed her parents and aims a gun towards him.]]
* [[http://www.youtube.com/watch?v=Eazctq0E-w0 Ante Meridiam]], the eerie yet saddening song that plays when [[spoiler: the human sacrifices discover that Father succeeded in taking all the souls of Amestris to grant him the power of a god.]]
* [[http://www.youtube.com/watch?v=eksvmp7RtSQ Clash of the Alchemists]], and [[http://www.youtube.com/watch?v=302Xbp7LRTo Spiral of Truth]].
* [[http://www.youtube.com/watch?v=Obmd6Z0K3mg Battle Scherzo]]. Whenever this song begins, a MomentOfAwesome is about to punch you in the face.
* Likewise, for [[http://www.youtube.com/watch?v=2eWVoHVzhxg Crisis in the North]]. Either Ed's kicking ass in the snow, or Olivier and her troops are about to show you -- and usually some hapless, pompous general -- why no one screws with Briggs.
* And from the third-and-final OST for ''Brotherhood'', we get some epic battle themes like [[http://www.youtube.com/watch?v=8KEcpz0IE3M "Knives and Shadows"]] and [[http://www.youtube.com/watch?v=q3FDnl2PkPs "The Awakening"]].
* [[http://www.youtube.com/watch?v=pN_ZRDX_vMo "The Land of Ishvala"]] deserves mention, if only for when it plays during [[spoiler: Lan Fan's return to fight gluttony in the forest.]]
* [[http://www.youtube.com/watch?v=XYxjP43-6u0 "Far East Suite"]] from the first Brotherhood OST. It doesn't appear on the show, but a [[http://www.youtube.com/watch?v=BFBe0Eolh48 pizzicato version]] plays in a lot of lighthearted scenes in the early episodes. Impossible to listen to without a smile on your face.
* The sadder version of "Lapis Philosophorum", [[http://www.youtube.com/watch?v=nCt4aLirnrk "Sorrowful Stone".]]
* Brotherhood's score has a particularly epic song called [[http://www.youtube.com/watch?v=a1VBeQlmJJA "Nightfall in Central City".]]
* [[http://www.youtube.com/watch?v=uvSGFg1MpXQ "Envy Revealed"]] is the music that appears when the villains take the upper hand, such as when [[spoiler: Lust gets the drop on Havoc and Mustang]] and especially when [[spoiler: Father opens the planet's gateway and absorbs God.]]
* [[https://www.youtube.com/watch?v=O8SfncLB964 "Philosophorum Omega"]]: The theme played where Wrath and Scar first come face to face and [[spoiler: when Edward is punching out Father.]]

[[AC:Other]]
* Quite a few of the songs from the first game are actually pretty good, but [[http://www.youtube.com/watch?v=tgs6vneghLg Fate's Crossing]] in particular.
* [[http://www.youtube.com/playlist?list=PLsmUoef7A22AzLR_jnHE-YwGQ9IJUYmwV The four battle themes]] from the ''Omoide No Sonata'' RPG for the Game Boy Advance.
* It's not official, but the the opening from the fan game [[http://www.youtube.com/watch?v=-J8MtOS4kTY Bluebird's Illusion]] is pretty good.
