In one of the Radio Interviews he was accused of being non versatile. What I gather from his response was that he is aware of this fact however he doesn't feel that he needs change. He is what he is. You like him or not. There are people who love him for what he is and there are even more who don't like him for what he is now. He can diversify his creations a little bit but there will always be a group of dissatisfied ones . THE most important of all is he doesn't want to change himself to please a larger chunk and find himself in the group of those who despise him. It seems like he is professional singer but music is still his hobby. I agree with him and may be that's why I like him more than any other contemporary musicians.
