Let's see...
I hate Rap, Hip-Hop, R&B, (don't call me racist for that, everyone does, but truth be told, my stepdad is black), Country, Contemporary Christian (Yes, I'm a Christian, but this stuff...sucks.) and those oldie songs when everyone sang in really high pitched voices.

The only thing I really listen to (and actually enjoy) is Rock (Van Halen, Guns 'n Roses, Collective Soul....and so on) and Alternative Rock (Green Day, MCR, etc.)
