Nothing's wrong with it, I found it hilarious.
But yes, I think most people do expect more than just music from a performer. Most bands do interviews, most bands sign autographs, it's a way of showing appreciation for the people who buy their records and come to their shows. You can't expect to be popular and not have anyone interested in you as a person at the same time, it just doesn't work that way. And if you don't expect anything from Bob Dylan other than is music did you skip through all of his interviews in his DVD, have you ignored interviews in magazines, would you be against Bob Dylan posters or whatever?
