'60s
The Beatles
Bob Fucking Dylan
James Brown
The Rolling Stones (their rich tradition of stealing from the black man is just too copied at this point not to list them)
Jimi Hendrix
'70s
Parliament-Funkadelic
Kraftwerk
Black Sabbath
CSNY
Ramones
'80s
Public Enemy
REM
Sonic Youth
New Order
Iron Maiden, although they're also 70s-ish, although they peaked in popularity here. They or Judas Priest need to be in this damn list somewhere.
Over all, I find these lists so far hilariously lacking in R&B and black people in general. I mean, seriously, I'm still thinking of bumping off the Ramones, CSNY or Black Sabbath in favor of Marvin Gaye or Stevie Wonder or something just to rectify the gaping hole. Motown and the subsequent rise of their greatest talents into more indepentent artists was a really, really big deal and the only reason it's not properly accounted for in my list is that I'm unsure who to give the credit to.
