Covers that are better than the originals
 

Blinded by the Light - Manfred Mann's Earth Band (original: Bruce Springsteen)

Lately - Jodeci (original: Stevie Wonder [sorry Stevie but it's true])

Any others?

Gwen Stefani covering It's My Life
Lemonheads' version of Mrs. Robinson

I prefer the Sublime version of "Scarlet Begonias", even though I think the Dead version is still great.

I think My Superhero's version of "Big City" is better than OPIV's, and it's not really close (not the best Operation Ivy track) . . .

. . . and that's without even getting into any sort of "All Along the Watchtowers" debate.
