I'll concede that Wolfgang is a genius & Bob isn't, if you like.

But so what?, as Hunter S. Thompson used to say. People are worth listening to or they aren't. Dylan & Joni Mitchell speak to me more than Mozart and I'd rather listen to them. Why should I listen to someone because he fits some definition?

A question like "Is he a genius?" is an intellectual excercise & the answer is of only academic interest and has nothing to do with the music.

The music don't give a good goddam who wrote or performed it.
