Why does black people never want to rock?

From November 30, 1963, to January 23, 1965, there were no Billboard R&B singles charts. The chart was discontinued in late 1963 when Billboard determined it unnecessary due to so much crossover of titles between the R&B and pop charts in light of the rise of Motown.[5] The chart was reinstated with the issue dated January 30, 1965, as "Hot Rhythm and Blues Singles" when differences in musical tastes of the two audiences, caused in part by the British Invasion in 1964, were deemed sufficient to revive it.[citation needed]

^^^ I see one guy in the discomusic thread asking the question but no one takes him up on it (unless I'm missing something)

Down to it, it's a good naive question to ask. And the last points I've just skimmed over are very sensible.
Cultural / race divide is its own answer, as music is closely linked to education, heritage, identity. There hasn't been much white presence in some genres that retain a strong black majority even to this day. You just have to ask black artists what they were listening and admiring to as kids. There's already been much talk elsewhere about the woman side of the history of music (how many listeners even approach 'equality' there ?), which is a similar social question.
