What's your favourite ost/op/ed theme from an anime series/show/movie?

Mine would be Last Exile for OST...
Tokyo Underground for OP (both) and... hmm... the second (or was it the third?) ED in GTO, that's my votes anyway

I like both FLCL and Shingetsutan Tsukihime OST's.

Maison Ikkoku for sure......

Rurouni Kenshin Tsuiokuhen & Seisouhen.

Best OST: Madlax (at the moment),
Best OP: Otogizoushi,
Best ED: Kurau Phantom Memory

Toss-up between Escaflowne, Cowboy Bebop, and Ghost in the Shell:Standalone Complex

last exile
escaflowne
.hack//sign
wolf's rain

can't decide

I thought that the OST for Full Moon wo Sagashite was very fitting as well, must be the best incorporated OST, me thinks...

.hack, noir, madlax, Midori no Hibi OP and ED, some sailormoon ost's (lol sorry but Sailor Moon was my first anime @_@) and alot more which i dont remember that's why i have here ma winamp playlist in HTML form enjoy

It's hard to decide between the two of them, but I would say number 1 is Cowboy Bebop (Yoko Kanno!) and number 2, FLCL (The Pillows).

Yu-Gi-Oh! Sound Duel 01

Best OST: Utena, Noir, .hack, and Vampire Princess Miyu

My favorite OST is Wolf's rain.
The ending song, 'Gravity' is my best songs.
Sakamoto Maya sings the song. And the melody is very beautiful.
I gladly recommend this song to you.
