I guess it just depends on what your mood is. If I feel like it, I'll blast techno, house, rap, reggae, anything.

If I wanna just lay back, I'll play chill-out music, which is a specific genre. I recommend Sub Zero: The ultimate Chill out collection to get into the genre. It's awesome stuff.

Actually, I usually can't decide what to listen to, so I'll just pop anything in. It's surprising, anything I put in is always great and trips me out anyway. I guess I'm just not picky when I'm high.
