Heh, I listen to just about everything from the Offspring to Coldplay to Beethoven to the Beatles, but currently I've gotten particularly addicted to '90s and early '00s hits (with notable exceptions [cough]Madonna, Backstreet Boys[/cough]), and classic visual kei... I'm amused by the fact that they have pretty close to nothing in common (other than having a slight chronological overlap).
In particular I've been listening to:
Dragostea Din Tei - O-zone
Rock Star - Smashmouth
Tubthumping - Chumbawumba
Rosier - Luna Sea
Blurry Eyes - L'Arc ~en~Ciel
Oh and 99 Luftballons by Nena (and a cover by Goldfinger).
