Yoko Kanno, Yuki Kajiura (though Yuki's songs get quite repeptivie(sp?) after a
few OSTs), -Key- (Air, Kanon), Kou Otani, and the composer of Ayashi no Ceres
Mine are Kenji Kawai (GITS movies), Hajime Mizoguchi (Jin-Roh), Yoko Kanno
(GITS: SAC) and Taku Iwasaki (Rurouni Kenshin OVAs). For game music, Nobuo
Uematsu (FF series) are my favorite.
DEFINATELY Yoko Kanno and Yuki Kajiura! I think most of us loves them!
Others are Kenji Kawai, Akifumi Tada (Yami to Boushi to Hon no Tabibito,Jungle
Guu,Final Fantasy: Unlimited ..)Seikou Nagaoka (El Hazard, Stellvia..), Mikiya
Katakura (composer of ALI Project),Taku Iwasaki (Robin The Witch Hunter,
R.O.D.,Black Cat), Kotaro Nakagawa (Planetes..)
Yoko Kanno, definitely. She just rocks. Although! Taku Iwasaki (Rurouni Kenshin
OAVs) and the ppl who made the bgm for Peacemaker Kurogane and Getbackers did
quite a good job.
Yeah, Yoko Kanno and Yuki Kajiura are my faves, and I downloaded the soundtrack
from Advent Children and there were some pretty good ones, a few really awesome
ones (can't think of their names), and the rest were so so, but the majority I
enjoyed.
I like one from gundam seed defintily

Yuki Kajiura is my favourite... even if I "discover" her quite recently. And she works with so many singers.
Yoko Kanno and Susumu Hirasawa are really the only two that stand out for me. They both do excellent work.
Shokichi Ishida from Jing: King of Bandits. The ending theme from Mai-Otome.
Yuki Kajiura all the way! She makes the best songs and BGM!
