My least favorite genre is dance-punk. I liked that !!! the first couple times I heard it, but it wore out real quick for me. Now, whenever I go to somebody's house, they're playing that shit.

Please add Rap/Hip Hop/Urban to the list. I mean, I really gave it a chance, honest. I used to blast the first PE lp in my Dodge Shelby! I still have the first NWA 12" made with Crip drug money. I just hate the new crap now, and whenever someone says "No, but listen to this.." it's still bullshit.
Smooth Jazz is a close second. "Yeah, I listen to Jazz.." Ugh, the Jazz station here in Mickey is the worst sub-elevator soul-less tweedling music ever.
