Good anime OSTs?

I think Naruto is a good OST

[Ichigo_89]

OSTs that I would recommend:

Stand Alone Complex
Appleseed
Last Exile
Samurai Champloo
FLCL

[Joshua Christopher]

Giant Robo
FLCL
Berserk
Gundam Wing

[TrigunX89]

FLCL is the only one I have, and it's great! In the future, I might consider Noir and Cowboy Bebop.

These ones I thought were particularly good. Ones marked with * are out of print, though!

Ranma OAV OST* (this one is --very-- hard to find, I had to special order it from Japan)
Nadesico CD-001 (this might be only available in Son May now)
Robotech 2-disc OST*
Fruits Basket Memory for You
Master Keaton OST (Japan only?)
Someday's Dreamers OST
Akira OST

[Maledicte]

Giant Robo--classical-inspired
Hellsing--garage band
Cowboy Bebop--Jazz, blues and all sorts of good stuff
Boogiepop Phantom--techno...stuff, I forget the correct term
Heat Guy J--Rock
RahXephon--mix of good things.

Hellsings was really really good.

[Arnobius]

Excel Saga (Import). Not so much the OP and ED as it was the background music

I liked Puni Puni Poemi's soundtrack (Import)... though there is a lot of stupid filler on it (it was only an hour long).

"Call Me, Call Me" from Cowboy Bebop was good.

Imports are generally too expensive to do though

As much as I disliked the series, I did like Utena's "Heavy Metal chorale" style songs. Would love a soundtrack to that if it's available

I don't know what you're into as far as music goes but these are the OST's I own:

His and Her Circumstances
Vampire Princess Miyu
Sakura Wars: The Movie
The American Sailor Moon Soundtrack
The Sailor Moon: Lunarock Soundtrack(ah! my middle school years)
Samurai Champloo
Noir v.1 and 2

[Puguni]

Haruka 8's track is pretty good; it's traditional Japanese music-ish and I like the ED better than the OP.
