Punkrock is the best! Notice I say punk ROCK, with an emphasis on rock. Some of the best bands out there: Turbonegro, New Bomb Turks, Rocket From the Crypt, The Hellacopters, Puffball, Randy, The Hives, No Knife.
Also indie pop rock is great: Built to Spill, Modest Mouse, The Flaming Lips.
I'm also a huge fan of Coldplay. At first I hated them because of their high-voiced British pop sound. But once I looked past my bias I found they were one of the better bands I've ever heard.
I also like one jazz band: Galactic. It's like modern jam-band-jazz. Amazing.
I hate metal, I hate most mainstream rap, I hate R&B more than anything.
And Warren, "Dropkick Murphys... that's what the preppy kids listen to

" Hahahahaha, wouldn't wanna ruin your deathmetal image with such a pussy band!!! Yeah just kidding if you couldn't tell.
