Hall of Fame should be artists that are a reference point of their style of music or a Larger than Life icon in popular music.
Dolly should have been one of the first names in the HOF period.
Never heard of mc5 or fela kuti until reading the first post.
Most of the other names are debatable, Eminem isn't rock but certainly brought rap to the main stream, Beck is mediocre for the alt rock he plays on par with Cornershop for instance, how are we listing RATM (who I like) in competition with Judas Priest (not a big fan)? Priest have been a hallmark for heavy guitar music since 1974!
