I was reading jfb's "Guilty Pleasure" thread and started thinking about George Michael's remake of Stevie Wonder's 1974 classic (co-written by Yvonne Lowrene Wright) entitled They Won' Go When I Go. Stevie's version was good but George owns that song. By comparison, Stevie is mumbling through it with half the emotion. Follow it with George's Mother's Pride if you feel the vibe.
I started thinking about cover songs that were better than the original. That, inevitably, made me think of remakes that were just an insult to the original performance and the person who wrote it (if not the same person). But things that I like or dislike might be the exact opposite for you.
So let's hear it. What are your favorite (and least favorite) covers? Post audio/video clips if you have them.
