For contemporary rnb act, I would also guess likes of D'Angelo, Erykah Badu, TLC, who are cooler to voters will be voted in more smoothly than likes of Mariah Carey...
Mary J has more rnb roots in her music and Sade has more artistry. They are definitely cooler and more attractive to voters and we know they are voted in over Mariah.
Coolness definitely matters for non-rock musicians, especially for black musicians.
Again, for rap acts, committee has to pivot acclaim over popularity/sales, only "popular" rap acts will not get the votes to be voted in.
You can basically assume popular but not acclaimed rap acts as a weaker vision of Mariah Carey in induction chance, and many voters (not rap voters) will "meh" or even be pretty negative on them... Popularity will hurt them rather than help them in this case.
Because many non-hip hop voters will feel that they are, too commercial, too pop-oriented
more like entertainment products, lacking the status of serious artists. This won't be problem for corporate rock acts but unfortunately will be probably for rap acts for rock hall chance of being voted in.
Acclaimed rap acts are more likely to make other voters (not just rap voters) say yes to them.
This is the current politics... Rock hall has to push WuTang, Tribe... rather than likes of MC Hammer, DMX... Because latters are not going to be voted in. Just like New Edition/Mariah lost to Wu Tang Clan in official voters voting.
Supertramp sold 70+ million. Meat Loaf -> 100 m. They are way above Frampton.
Blue Oyster Cult -> 25m.
Frampton -> 20m.
There needs to be some logic behind these inductions. Yes, record sales are not everything, but still, 20m lifetime record sales is not impressive. Fluke one album wonders like Hootie and the Blowfish match / exceed that. Bush has 25m record sales and I don't think they are worthy. Collective Soul has 15m -> clearly not a strong contender. Live sold 20m and nobody mentions them.
Black Crowes sold 30m. I'm down on their induction mostly because the Rock Hall skips 100m selling acts like Motley Crue, Scorpions, Coldplay, and Linkin Park for them. They are a filler band, but I'd select the best available and let the voters decide vs tilting the scales and adding junk candidates like Buckley (musical excellence only). Also, the idea that newly eligible acts can wait longer is going to backfire when these bands finally get in -> they will have broken up already and won't perform. Same mistakes are being repeated.
