I listen to lots of metal mostly, I'm not picky with metal, as long as it doesn't suck. Death metal, black metal, thrash, power metal, folk, doom, metalcore, again, as long as it doesn't suck.

Then when I need a break from metal I'll listen to grunge, classical, hard rock, and J-rock. Then again with music, as long as it doesn't suck I'll listen to it. I just focus most of my resources on metal mostly.
