EDIT: ^While I have nothing against metal as a genre, I do have to admit I don't really like Metallica. As for talent, their guitarists are in no way BAD, but they aren't ludicrously talented either. And the bassist is given way too much credit. I can play pretty much any Metallica song given probably fifteen minutes to work on it (memorizing is another story; their riffs meander for ages). And their drummer just follows standard rock beats for the most part.
I like absolutely anything that fits some criteria:
A) Good lyrics (unless it's instrumental, of course)
B) Use instruments (real instruments; a human beatboxer is not an instrument, a turntable is not an instrument, and a trashcan and a broom is definitely not an instrument)
C) Actually care about their music
If that's all good, then I can like it (if it sounds good). I can listen to anything from metal to classical to punk to modern rock. Basically anything in there's good with me, though I am a softy for cool basslines.
