Paul McCartney 3

"Music is subjective always, but he is admittedly the greatest living musical artist of modern times."  

Admittedly? I think you misused that word, but I'll assume that you mean that everyone agrees that he's the greatest, in which case I think many if not most will disagree; myself among them. 
Anyway, past acheivments have nothing to do with his latest work. Like one of my old bosses used to say, "Yesterday's peacock is tomorrow's feather duster."

Everyone respects him so much from the Beatles days, and I completely understand that; but now it's like the king's new clothes. Nobody wants to say that his music is really weak. 
I've been there since the beginning of the Beatles, and I have no problem whatsoever with an artist exploring new sounds and changing styles; but to me, even the best of the Wings era was sort of silly and childish. Even the lyrics were embarrassing. But like I said, in the name of his past accomplishments, a lot of people feel bad about admitting that.
