What kind of music do I like? Hmmmm. Well, anything that's good. It's a long list but let me give you the basics.
Seriously, go listen to some ISIS or Pelican or Cult of Luna or Rosetta or Neurosis or RWake or If These Trees Could Talk they're all good and they all offer something different.
Yeah, it gets hate, but I like it. Consult my "Soul Torn" station if you want to get the best of the best. Personally I hate nonsense like Radiohead/Coldplay but whatever.
The very best power metal band out there. Without question. Hammerfall/D-Force SUCK compared to these guys. If you want heart/soul in your epic P-Metal, go Kamelot.
Listen to them, come back and talk to me.
SoundGarden > AiC > Nirvana > Pearljam = Live = STP
My equation, but they're ALL great.
I like Electronic stuff every once in a while, Assemblage 23 maybe some glitch mob.
I can't stand most rap, a couple songs here and there but in general, no.
Any modern pop stuff pretty much sucks.
