A few things from my last.fm (I like introducing people to music so they're non-standard stuff):
Ging Nang Boyz: Japanese punk-pop unit that screams about sex and acts like Iggy Pop on stage. They're getting some notice in the west since Jeff Rosenstock of Bomb the Music Industry! and Shinobu have both covered their songs.
Shinsei Kamattechan: If The Flaming Lips never evolved out of doing acid punk and kept that influence through the remainder of their work, they'd probably sound kinda like this. Punk vocals and guitar with multi-layered synth/piano melodies. Their frontman and songwriter Noko is about as crazy as Wayne Coyne and as musically talented as Steven Drozd. Their album Tanoshii ne is available on US iTunes now, and it's their best work to date.
The Radio Dept.: Mellow shoegazey pop. Labrador, their label, is putting out some of the best pop music in the world right now.
Shoji Meguro: Primary composer for Atlus' Shin Megami Tensei series of games. He flits between musical styles often; he's one of the most versatile composers I know. My favorites are his synth-rock scores for Shin Megami Tensei III: Nocturne and the Digital Devil Saga games, and his more poppy score for Persona 3.
Adebisi Shank: High-powered math punk. I recommend seeing these guys live; they put on a hell of a show and they're super nice and down-to-earth dudes.
