No need to break up that category apparently. Al Green is NWA is James Brown is Beyonce Knowles is the Brothers Johnson.
At least I have a classic R&B station on my digital cable (on right now Dazz---Brick) which plays some good stuff, but what is with the stuff from 1986 being played? There oughta be a law.
No, they do break it up into about six different categories (I looked into it for my car - I'm so damn sick of Clear Channel!)
