Irish singer SINEAD O'CONNOR's self-imposed exile from the music industry keeps her sane, because she finds fame too "painful". The Nothing Compares 2 U hitmaker, 40, likes to balance time in the spotlight with time for herself. She says, "Fame and beauty together have proved a curse for me. Fame, especially. It's the reason I keep leaving the game. I find it painful, I really do. "To be a good artist you need to be terribly sensitive. If you are sensitive then you're not well-suited to the vileness of the music industry."
