I was gonna say Gospel music cause that's like music based on black churches. Like I said too before the internet it was a lot easier, but back then you could also go platinum within small groups. Now you need to reach like 100 million to sell 1 million, back then you could reach 1 million to sell 1 million. (#s obviously outta my damn ass but you get the point).i dont know. There were a few artists in R and b who went platinum who i still believe had an all black fanbase. Now this is my opinion but ill name some artists that i think had an all black fanbase.
1. Keith sweat first 2 albums. White people didnt get into him until Twisted. I bet you white people never heard of make it last forever
2. Gerald levert or Levert-
3. freddie jackson. im sure there are more than this.
Like Gerald Levert peaked at #17, #18 and #48 and went platinum according to wikipedia. #17 this week is 10k sold, #48 is 5k sold. So you can put that in perspective relative to todays artists, K Michelle was #2.
