Prince is my favorite artist of all time and I'll agree with those who call him a jerk. Refuses to let his videos on YouTube (and YouTube is actually a great way to expose people to music beyond his hits... he doesn't get that), shuts down fan sites and sues those who run them, has notoriously gypped his fans out of money with web sites that he ends up shutting down after getting their money, will not allow Warner to remaster his albums, won't allow the release any of his classic tours on DVD, fires members of his band out of nowhere and won't speak to them (many of his former bandmates and associates have horror stories), etc...
Having said that, I love the mans music and his gift of talent that I can overlook all of that. But I still think he has pretty big shoes to fill in terms of being a jerk.
