The RRHOF is a joke. More than half the performers in the RRHOF do not belong in a true Hall of Fame which honors the best of the best, the performers who create a genre, or changed the genre. Ricky Nelson was inducted in 1987. Nice singer, but one of the best of all time?
The Kinks, Byrds, Booker T and the MGs, Yardbirds, Animals, Ramones, and so many more were all nice groups, even really good groups, but to me do not belong in a Hall of Fame. The Byrds were around for a few years and had a couple of hit songs. The Yardbirds were very short lived and although Eric Clapton got started in that group they were not HoF worthy. Cream is in so Clapton was honored in that group which is more appropriate.
Just keep in mind all of these groups entered the HoF years before bands like the Moody Blues, who had hit records and top albums for decades and brought new sounds to popular music. There are other bands that have been excluded as well.
There are too many performers in the RRHOF. It is watered down to the point where just about everybody who was popular for a minute gets in. I expect Hoobastank to be inducted in a year or two.
