Bands I think suck...
Disturbed - Always hated them, even before the tour thing. More or less I hate the fans and the singer with the monkey complex.
Queensryche - Fuck Queensryche.
Opeth - Not that they suck, I enjoy their music, I just think they're the most overrated band in metal.
Nirvana - Fuck kurt, i'm glad he ended himself so I didn't have to.
Trivium - So you met Dimebags wife, partied with her a few times... so why is it every time I see you, you cover 2 pantera songs? Oh yeah, cause your own material sucks ass...
Anything played on "alternative radio"
And probably a lot more, those are just the ones I feel strongly about.
