Let's just stop here and agree that the entire musical oeuvre of Yoko Kanno is a Crowning Music of Awesome. Sort of like how every chapter of the Summa Theologica is a miracle. This era's Mozart or Beethoven. God of Music. You get the picture.
"After, in the dark" is a rocking '80s-style open-air concert performance that plays over the first episode fadeout, and at the beginning of the Sharon Apple concert. As an in-story product of the virtual idol Sharon Apple, it really makes me buy how an AI could have become a mega-popular performer in the Macross universe. This is crucial to the plot, you see. ;)
Macross7's OVA sequel Dynamite 7 has "Angel Voice", even Basara haters have to admit that this song is pretty awesome. Think about it, "Angel Voice" is basically JAM Project and Yoko Kanno together in one song! You can't get any more awesome than that.
Becomes even better when you consider that Mari Iijima (Lynn Minmay) did her own version. That was awesome enough on its own, then the fans mixed it with the original, the result is sheer musical awesomeness as well as a Crowning Moment of Awesome for fan mixes.
White Dove, the opening recap for the series for the first few episodes, awesome enough from just that until you listen to the soundtrack version and you realize that, Hey there are words in this song!
The amazingly beautiful "Story of Escaflowne" that's played during the finale. If the ending doesn't make you misty eyed, this will.
"Arcadia", which accompanies Hitomi's vision of the Atlanteans' ancient doomed utopia, and her final epiphany about who she truly loves at the end of the series. Exquisitely poignant dissonances in the strings form the introduction to a literally operatic piece (it's an honest-to-god aria). Transcendentally beautiful.
Heck, ANY track from the Escaflowne soundtrack is epicly gorgeous! Revenge, Farewell, Murder, Angel, Wings, Gloria, etc...
From the Escaflowne Movie OST, "Take My Hands" is an emotionally powerful interlude in the soundtrack when Van's wings are revealed while rescuing Hitomi. Seriously. The last stanza is used in the opening of the Escaflowne Movie DVD.
One of the most AWESOME endings in the history of anime segues seamlessly into the beautiful "Blue". Roughly 90% of anime fans want that song played at their funerals.
The ending of the final episode is one of the few end credit sequences to an anime series that [adult swim] doesn't speed up to get in more advertising time (including most other Cowboy Bebop episodes after the initial run). "Blue" is just that PERFECT an ending to the series.
Not only is the music amazing on its own, but the fact it is used during a protracted dogfight/chase with main character Spike, using what are essentially futuristic fighter jets. Surprisingly, it fits the scene perfectly.
On a similar note, "Elm" shows that even in the middle of a chase scene, the right song can turn it from being about catching the bad guy to an internal, emotional struggle. Just try replacing this song with anything else, and Jet's chase scene will be nowhere near as powerful.
The melancholy Road to the West could be described as a saxophone weeping lyrically for 3 minutes. As one of the comments states, "If I ever break up with my girlfriend and I find myself driving on the highway at night alone, while it's raining, still remembering her and the times we had, this is the song that would be playing in my head." This is actually the emotional context in which it was used in the series.
The Wolf's Rain soundtrack. "Stray", the theme song, definitely deserves a mention. The song is reminiscent of all the most epic 80s power ballads, with Steve Conte's voice making it even better. And then there's the frankly brilliant moment where the guitar makes a howling sound, just as a wolf is shown howling...
"Gravity" is just such a wonderfully, beautifully melancholy song, that it deserves to be included here.
The final track, "Go To Rakuen", with its gentle piano and heavenly strings, is really indescribable. Also the heartbreaking "Shiro, Long Tails" that played during some of the most emotional battles.
"Strangers", sung by Raj Ramayya. The haunting trumpet, the soft vocals, the lyrics filled with desire and hope that lets you believe the wolves really could make it to Paradise. At the same time this makes it very sorrowful, but still no less gorgeous.
"Cloud 9" practically has awesome written all over it!
The soundtrack for Ghost in the Shell: Stand Alone Complex is really, really good. There isn't really a single track that isn't marvelous, they always blend perfectly with the visuals and context of the scenes they're matched with, and they play a huge part in making the show so amazing. It's possibly one of the greatest soundtracks ever made.
If you don't absolutely HATE everything that this song is, then it's not doing what it was supposed to do. "Go DA DA" is just as it's described: The most malevolent and ominously evil sounding song you'll ever hear. It's supposed to instill scorn from the listener.
It's hard to find any song that's better than "Stamina Rose" to kick off any anime, let alone TV series in general.
Torukia could also easily be the best track in the OST.
It's also kickass in a capella Gregorian-like slow choir-only version in episode "Poker Face", when there's a sniper duel on a hospital roof.
Also, "Ride From Technology". Sounds like a lost masterpiece from Cowboy Bebop, definitely great. And Fish/Silent Cruise. Such a dramatic song with such a power,purely awesome. And what about the great Jam Rock masterpiece which is called Yakitori?
The song beauty is within us(lyrics), specifically written for the episode that features it, "Runaway Evidence TESTATION", perfectly conveys the anguish and enigmatic motives of Kago Takeshi.
Run Rabbit Junk. Every time this plays, Section Nine is doing something awesome.
How about I Do, the beautiful Italian song that plays throughout most of the tear jerker scenes in 2nd Gig.
If you didn't start crying when this song was used in context with the episode "Affection", then you truly have no soul.
And then we have "Waratteta" with vocals by Mou Sukoshi.
Kids On The Slope. A series that is essentially a 12-episode-long love ballad to jazz. From the first song on the OST, to the last note in the closing theme, each piece of music is just beautiful. However, what really stands out is the "Medley" from Episode 7. It will leave you in tears.
