Honestly, I don't think many of the groups/artists people have listed will make it into the R&R Hall of Fame. If it was a specialized one from Soul Train or Vibe maybe but the main one??
Prince made it in his first time eligible but he's a musical genius

. They may not accept him but they can't knock his talent.
The Dells made it this year - but it was their 4 or 5th time being nominated. I was surprised during their acceptance speech when he listed groups that have not been inducted/nominated yet - (The O'Jays & The Stylistics)...if these groups that still sellout concerts and have reunion tours 30 years later are having trouble getting votes I don't think too many of today's artists will ever be considered.
However, my short list of future nominees includes:
Babyface
Barry White
Celine Dion
Janet Jackson (if she stays out of trouble)
Jimmy Jam & Terry Lewis (producers)
Lionel Richie
Mariah Carey (*would have to put out a few more albums)
Outkast (if they stay together)
Patti LaBelle
Whitney Houston (*see JJ)
And if they go there then I'd have to include Dr Dre and Ed Lover for hosting Yo MTV Raps...because of them this cross over stuff happened
Here's the link to see who's already been inducted
