He's clearly a musical genius and his ability to harmonise is beyond words.
However when I first listened to him, my reaction was "this is very impressive, but I don't know why, I just don't feel it". What struck me was that when I read up on him a bit more, that was a pretty common reaction among people.
I don't really have the words to describe any of this. There's just something missing there. Soul. Which is a strange thing to say, because he probably does pour his heart & soul into his songs.
