She is popular because of her voice, the character in it, the intonation, the magic that is Stevie Nicks. These lyrics are her usual live lyrics. You would know this if you followed her many other live sets, including the very early versions. I love the people who sit and say that this phenom isn't so great. Surely you jest.

This may be the best I've ever heard Stevie sing. Usually she doesn't exactly have the smoothest voice, and not always the best pitch either. She didn't get popular because of her astounding pure vocals, no matter what she or anyone thinks.
