I like pretty much anything Godsmack.... I like Linkin Park, but they need to get some more songs going.
I'm not that much of a music person, anymore. I like most game music.... If I could spell his name right, I'd say it, but for now, I'll just say "Final Fantasy music composer."
Jun Senoya (I think that's his name...) does most of the Sonic Adventure music, and that music isn't too bad, for American translated music.
On the other half of my brain (no, not literally), I like Jimi Hendrix, Lenny Kravits, and even Eric Clapton. I'm one of those damned guitar freaks, but I play the drums.
