To qualify for induction 25 years must have passed since the release of the band/artist's first album. I think the following performers are a bit overdue for induction into the Rock and Roll Hall of Fame and should be the five inductees next year:
The Stooges. Qualifications: Released first album in 1969. Iggy Pop and the Stooges were a pioneering band in that they are credited with influencing both the development of punk and heavy metal.
Kraftwerk. Qualifications: Released first album in 1970. Pretty much invented electronic music. Without them: no techno, no synthesizers and vocoders, and no endless sampling of 'Trans-Europe Express'.
Roxy Music. Qualifications: Released first album in 1972. "Roxy Music were a huge influence on both punk and New Wave: They anticipated the restraint and the coolness of the Eighties, but you wouldn't have had the Sex Pistols without them, either." - John Taylor of Duran Duran.
Gram Parsons. Qualifications: Released first solo songs in 1973. Generally considered one of the founders of country-rock, a notable contribution to the rock and roll field.
Whitney Houston. Qualifications: Released first songs in 1985, and the Hall o' Fame can't resist such a qualification. That, and she's one of the best-selling artists of all time, and generally well-loved. I'm more confident in her getting in next year than any of the others above.
