I believe no genre of music is bad as such, but also that 90% bands of every genre deserves to be raped in the spear wound through their eye.
I would, however, decaptate David Haselhoff for making a hip-hop record which I don't ever want to hear.
Tool have their qualities, but their music makes me feel bad (sick). Not to mention the videos.
I was really disappointed in Audioslave, since I like both Cornell and Morello, but I wouldn't get overexcited.
I would slay Staind but I don't think anyone would notice, they'd get a substitute within a few days. Same goes for Linkin'.
Short list of those who would enjoy a slow and painfull death: Celine Dion, Mariah Carrey, Brian Adams, Jon Bon Jovi, Courtney Love, Chris Impeliteri, Slipknot, Foo Fighters, Blink, Sum... Actually, if I sacrificed all of them to Satan, he might be willing to ressurect Dime and Johnny Cash, or at least reincarnate them propperly marked so they are easy to find. Hmmm...
