I'll probably think of more later, but I have to agree with Korn. They're first album or two were decent because it was new at the time, but go home and shut the fuck up already. Actually, Korn wouldn't be so bad if they didn't spawn hundreds of Korn clones that is the nu-metal scene of today.
I also could have done without almost everything my sister listened to in the 80s, because I had to share a room with her, and was subjected to all the stupid crap teenagers were into at the time, which unfortunately for me, was NOT metal (she's 10 years older than me). Of all the crap on her walls and in her stereo (Michael Jackson, Menudo, every one-hit wonder there ever was, etc.), The Police was the only band that didn't make me want to kill myself. And my mom wonders why I was outside every minute that was possible...
