As has already been said, he is very talented, but kind of creepy.
I like SOME of this music very much, indeed, although some of it I don't care for. I respect his musical talent, and his flair for showmanship.
But I think the man appears to have a few serious issues psychologically, and with regard to his identity and sexuality. Some people would suggest that that goes hand in hand with great creativity, but I don't think it has to. It just does sometimes ... as in Prince's case. Gifted composer, arranger, guitarist and musician in general ... but a little weird as human beings go.
