So was MJ (according to folks), but he is not top 50 as a vocalist either...
Musical genius?,, not in my book..gershwin, Porter, Mercer , Kern, Kahn..and a dozen more from that era...They were true musical genius.....The latter Pop artist were dependent on repetition beats, hooks, and appearance...and as one dimensional as they could be.....
I am not sure, music will ever be at the level of the 40's..in all genres...
Fran try to tell that to today's generation..
