Uhhh....They missed a few, the put a few decent bands in there (Kansas?) and forgot the ones that truely make any lover of instrumentation's skin tear itself apart and flee screaming. Lenny Kravitz (yes there is a band there) For his uninspired bubble gum shredding of many a good songs, he takes uncreativity to a whole new high by getting famous off of covers. Metallica, OMFG Metallica, where to start, Oh, yeah they suck, they have little if no skill at anything they do, and they do it in a pentagram. Satanism and poorly written music backed up by a propaganda machine that would make Bush weep with envy.
And I agree with Storm Rider, Primus may have lacked lycical ability, but the absolute genius of Les Claypool as a Bassist by far makes up for that. Limp Bizkit is like a combination of the worst of a triumverate of evil (though the bassist was good) It's like someone took Vanilla Ice and injected him into the Danny Divito clone of Lars Ulrich, and then mixed it with a distorted version of Spinal Tap.
