Yeahh, he's a big star but you guys don't have to talk down to someone for not knowing him. Not everyone knows everyone and I'm sure anyone could not know who he is.
Yes, I definitely knew him and I'm kind of a fan of his work
That said, people are doing too much on the OP. Everyone knows this boards skews younger, has lots of international posters, and skews towards pop music. So I wouldn't be suprised if a lot of people here didn't know an almost 50 year old R&B male artist who hasn't had a major hit since 2003
