Little of this a little of that. Some constants on my varied playlists:
Dubstep, Poets of the Fall, Wood Kid, The Decemberists, streelight manifesto The Black Keys, Medeski Martin and Wood, Rage against the machine, breaking benjamin, airborne toxic event (select songs), Led Zeppelin, The Fray, Nas and Damian, King Crimson (select few songs though) among others that I can't think of right now.

My collection of music grows almost exclusively through people I know suggesting bands to me so there are a lot of individual songs that I have and like as well
 
I go to a lot of raves personally, drum & bass and dubstep are my top choices as of current.
