The Rock and Roll HOF really should be renamed 'The American Music' HOF.
It recognizes American-born musicians - individuals, groups, and bands (along with songwriters, label executives, etc. - correct. me if I'm wrong)...and artists from other countries whose music became extremely popular in America.
Popular and groundbreaking artists from the early 20th century on are inducted from many genres ( Jazz, Gospel, Country \ Bluegrass, Disco Music being the exceptions - again - if I'm off base - set me straight). Blues, R&B, Soul, Pop, Funk artists have been awarded the honor.
Change the name of the honor and museum. Then someone start an in an organization that just recognizes true rock & roll - rock music.
