Utada's CD bombed because of that damn Japaneesey song. I felt embarrassed just listening to it.

I like 90% of all of TM Revolution's songs. But I like most of the Gundam sound tracks and Nobuo Uematsu, he is the #1 composer of the 21st century for a reason. =]

Yeah, mad props to Miyavi too. Style-wise he reminds hide a lot. Obviously different, but he is really good. He had the balls to go from full-visual to almost-full-pop without a breeze. Rock rawk rock rock!

My favorite Japanese COMPOSER would have to be Yasunori Mitsuda (Chrono Trigger, Cross, Xenosaga), but I'm not sure if he's done any recent work...

There are so many to choose from...

Onitsuka Chihiro - Infection - Very powerful voice with extremely well composed songs.

Yonekura Chihiro - Forever Gate/Eternal Door - Very active fast paced songs.

Kotoko - Agony - Fast paced, good rhythm.

Kajiura Yuki - A Song of Storm and Fire - Probably the best current Japanese composer around.  The vibrance found in her work easily eclipses that a lot of others even Kanno Yoko.

Two Mix - Love Revolution - Good group specializing in a lot of synthesized music that did a lot of Gundam music particularly Wing.

Chiba Saeko - Here We Stand In the Morning Dew - Great voice that can literally overpower the music (song composed by Kajiura Yuki).

So many great artists left unmentioned, yet so little time...
