I never really liked their production and they pretty much say the same thing on every song. At least that's how I hear it.
Maybe its just because of where I'm from and the unwarranted popularity they have there.
I really can't stand their fans though. black dickies shorts, black tank top, high black skin brand socks wearing skinheads shotgunning bud lights while driving lifted black trucks across glamis reminiscing about their last trip to glamis trying to fuck the bitch with the biggest muffintop and 4th grade caliber drawn starred tattoos on their 2nd roll under their belly button ass bitches.
