Metallica (died in '86 with Cliff Burton. AJFA was a fairly weak effort by them, the black album was the most overrated album of all time and Load and everything since downright sucked).
U2 (they suck and they get all this attention like they dont)
Dave Matthews (cant write songs, not original just takes stuff from different people nobody has ever heard of)
Nirvana (they get famous because mainstream had already sucked as much as anything could suck until these guys came along and proved it could suck even more. As if Motley Crue already didn't lack talent badly enough, these guys thrived on no talent. Kurt Cobain dies, so does the band, and people quickly begin to forget they ever existed).
Slayer (all we ever needed from them was Reign in Blood. Everything else was weak in comparison and they got old real fast)
Van Halen (the first album was great... but what the hell happened after that?)
Pearl Jam (none of them have died yet, but we wouldn't miss them if they did)
AC/DC (they are okay, but they are definitely not worth all the fuss)
Motley Crue (how much three cord lack of creativity and cheese can you fit into a song?)
Poison (they suck too - somebody explain to me how Bret Michaels gets around so much? If I looked that feminine, all women would think I am gay... oh wait he probably told them all that he is gay and wants to see what sex with a woman feels like)
Queen (as if the name wasnt enough!)
Prince (... do I really need to explain?)
Village People
Bee Gees
All disco in general
All rap. Love it or hate it, it's still not music.
Britney Spears
All boy bands
All mainstream for the past 20 years
am I missing anyone?
Those who are rightfully famous (who have done something to deserve it, whether or not it was creativity to create a new style of music or to refine it or by excellent musicianship)
The Beatles (not the biggest fan or anything, but they took rock to new audiences all over the world. I mean to date for what's out there they are still overrated, but they earned some of it)
Iron Maiden
Led Zeppelin (as overplayed as some of their songs are.... stairway *cough*, they have done more than anyone for hard rock and metal, and no one will probably ever do as much for a genre as they have. After all, we had over a decade of bands who want to be them).
Dream Theater
Steve Vai
Joe Satriani
Eric Johnson
Deep Purple
Judas Priest
Pink Floyd
SRV
Megadeth
Jimi Hendrix
Rush
The underrated:
Bozzio Levin Stevens
Gary Moore
Steve Stevens
Frank Zappa
Fates Warning
Tony Levin
King Crimson (21st Century Schizoid Man has to be the best stoner music I have ever heard!)
