I take offense for Stevie Nicks. There are two reasons.
1) I can't believe that she sang back up for Taylor Swift at the Grammy Awards! I actually am a fan of Taylor Swift, but Stevie is such an icon that she really shouldn't be singing backup for a pop star!
2) Taylor Swift sounded like I do when I sing Karaoke- flat and out of tune- basically horrible! Poor Stevie having to put up with this new generation of pop who can't hold a match to her singing!
