I just like music that involves a lot of complicated stuff like Jazz chords and shredding down modes. I find it nicer to listen to that just strait power chords.
I do like tons or other music, everything from classical to death metal, but I just dont like Slipknot, I suppose its the yelling and the same old power chords, and lack of playing lead. I guess its just that, I'm not the kind of person who listens to music for the message, or lyrical content, I listen to the instruments in the music, and as far as vocals go, I usually analyse a singers voice as if it were an instrument.
