Awesome Music / Fullmetal Alchemist

    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 the 2003 series:
  • From Brotherhood:
    • The first opening theme "again", which, like "Brothers", is both heart-wrenching and beautiful.
    • "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 "Golden Time Lover", the third opening, makes up for it through sheer catchiness.
    • CHEMISTRY gets music of awesome with "Period", the fourth opening. This is the best way to start an episode.
    • The 5th Opening "Rain" by SID is too beautiful for words. The 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 Chapter 104. Everyone is "dead" and Father appears to have won. It doesn't play until 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 awesome and heartwarming. The use of the 5th Opening at the end of Episode 63 is incredibly satisfying as a Heartwarming Moment AND one of the biggest Tear Jerkers of all time...
    • "Uso", the first ending to Brotherhood is both catchy and touching.
    • The second ending song of Brotherhood, "LET IT OUT", is beautiful on it own, but when paired with the ending scenes... Moment Of Awesome/Heartwarming.
    • The third ending theme, "Tsunaida Te", is quite uplifting.
    • "Shunkan Sentimental". The first few chords, combined with whatever epic event ended the episode...
    • "RAY OF LIGHT", the 5th ending theme to Brotherhood.
    • The theme songs of the Brotherhood movie, The Sacred Star of Milos: "Chasing hearts" and "GOOD LUCK MY WAY".

2003 Series
  • Bratja alone is considered one of the finest pieces of music ever written for an anime.
  • From the very first episode, we have Way Back.
  • The 2003 score features many awesome pieces. Amestris, Way Home, Invasion, Daring Fight, Greed, Shinryakul, and Seiatsu are just a few examples.
  • 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. 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 Image Song for Ed, and it's quite badass.
  • "Aishou", Lust's theme.
  • Dante's leitmotif from the first series, "Dante."
  • "Koukai" is easily one of the saddest tracks in the first anime.
  • Whenever Tsumi plays, you can be sure that something either awesome and awful (or both) is going down.
    • Same with 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!"
  • Homunculus, as well as its thematic reiterations (like Romei).
  • "Trance to Homunculus", an absolutely epic Villain Song for the Homunculi of the 2003 anime, even if the "lyrics" are just quotes by the Homunculi from the show.

Brotherhood
  • Mortal Sin (played the first time Ed meets Lust and Envy).
  • Trisha's Lullaby (used to great effect when Ed and Al mourn for Nina).
  • 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 when Mustang reveals his plan to fake Maria's death, and again when Wrath makes his grand re-entrance back in Central.
  • Lapis Philosophorum (heard in the first episode).
  • Xing Symphony -Overture, the theme for Xingese characters.
  • To Be King.
  • The awesome theme which kicks off the battle between Mustang and Envy, The Intrepid.
  • Versus Homunculus, and its remake 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.
  • Pride is also an excellent theme.
  • Major Armstrong's theme, also known as Amestris Military March. "COURAGE INCREASED BY ONE HUNDRED FOLD! MUSCLES INCREASED TO ONE THOUSAND FOLD!"
  • Requiem for the Brigadier General (referring to Hughes)
    Youtube Reviewer: "Mommy.. why... why are they putting dirt on Daddy? Daddy said he has lots of work to do!" I. BROKE.
  • The Main Theme.
  • Dissident's Creed, the music when Winry finds out that Scar killed her parents and aims a gun towards him.
  • Ante Meridiam, the eerie yet saddening song that plays when the human sacrifices discover that Father succeeded in taking all the souls of Amestris to grant him the power of a god.
  • Clash of the Alchemists, and Spiral of Truth.
  • Battle Scherzo. Whenever this song begins, a Moment of Awesome is about to punch you in the face.
  • Likewise, for 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 "Knives and Shadows" and "The Awakening".
  • "The Land of Ishvala" deserves mention, if only for when it plays during Lan Fan's return to fight gluttony in the forest.
  • "Far East Suite" from the first Brotherhood OST, despite not appearing on the show.
    • Also the pizzicato version that plays in a lot of the more lighthearted scenes in the early episodes. Impossible to listen to without a smile creeping onto your face.
  • The sadder version of "Lapis Philosophorum", "Sorrowful Stone".
  • Brotherhood's score has a particularly epic song called "Nightfall in Central City".
  • "Envy Revealed" is the music that appears when the villains take the upper hand, such as when Lust gets the drop on Havoc and Mustang and especially when Father opens the planet's gateway and absorbs God.
  • "Philosophorum Omega": The theme played where Wrath and Scar first come face to face and when Edward is punching out Father.
