I hope very much that someone new comes along and shakes things up, because rock at this point, as a mainstream art form, is basically dead. Nearly everyone popular is borderline useless, and will be totally forgotten in five years. IMO Radiohead is the only big band doing anything remotely interesting anymore. There's lots of good underground rock and rap, but it seems much more difficult to find than it used to be.
So, heh, rather than listing poor bands, let's just say that if they're on the radio or MTV, chances are very very good that they suck. All the crap-ass metal (Korn, Limp Bizkit, Linkin Park, 8 million other faceless bands), crap-ass pop (Britney, Christina, the usual suspects), crap-ass mainstream rap (Nelly, Puffy, etc.), crap-ass Pearl Jam-wannabes (Creed, 14 doors down or whatever, etc.), crap-ass pop punk (Blink 182, etc.), and crap-ass jam bands (Dave Matthews, etc.)...it's all worthless. Worthless, I tell you!
Joey Ramone dying was the last straw. I wish all you damn 18-year-olds would get busy and produce another Kurt Cobain. Except without the suicide. Get crackin'!
