I am a confirmed, since-the-beginning, "hard-core" Sade fan..
for the group's career
(like this, pzlyprk??)
nothing in their stellar, brillian career really screams "rock n roll".
in fact - Sade (the group) & Sade (the singer) should have their own personal Hall of Fame,
to be honest about it..
though most of (the group) Sade's music has elements of & bites off of jazz.. they are not a "jazz group" in the traditional, real sense of that phrase. before rock n roll became popular in the mid-50s, you know there were the "pop standards" with singers like Sinatra, Bing Crosby, etc.. then all the big bands, the real jazz musicians (& their music) as well as classical music. "rock n roll" is basically (or WAS, basically?) a convenient catch-all phrase to fit what Chuck Berry et al started doing back then. rock n roll today seems to include any type of popular music, including groups you normally don't associate with "rock n roll". groups like CAMEO..
I wouldn't imagine the other (male) members of Sade would be too put off - if at all - that people associate their band with their exquisite lead singer. those dudes are great musicians & they are still gettin' paid. they know - & probably would agree - that Ms. Adu deserves all the attention she gets and has gotten.
per the others mentioned (& summarily dissed from the Hall this time):
Janet Jackson shouldn't be in there. at her peak she was a pop music/pop culture icon whose biggest hit woud be "you don't stand another chance".. if Jimmy & Terry hadn't gotten stuck in the snow
Whitney could get in, maybe should get in.. just from the power, skill & beauty of her voice
(I personally didn't like most of her music - it was all too "calculated pop syrup crap" for me)
the RRHoF is definitely a "good ol' (white) boys' network. probably why Chic hasn't gotten in yet. I imagine they will, eventually. Chic as a group, & Nile Rodgers as a producer should get in too.
Lenny should be in. he should be in FIRST BALLOT.
War should be in - any version of the group.
I'm on the fence about Living Colour. their music overall is solidly good, but if they were caucasian would they have had as much attention??
in the end, many groups & performers would be worthy of getting in this Hall..
but politics plays a big part of it.
as it does in most things.
