Fuck, I listen to everything - usually stick 250Gb of music on random and it does get very random. (Just had Bowie->Lennon->Some trance track->Saul Williams->Ani DiFranco->Metallica)
A few current faves:
Pendulum
Billy Bragg
Portishead - Their new album is amazing!
Infected Mushroom
Arcade Fire
Nick Cave
Pink Floyd (always love a bit of Floyd!
)
