Cover songs that are better than the originals.

There have been several versions of "Sweet Jane" mentioned.

I like Mott The Hoople's version.

Sympathy for the Devil - Motorhead

1. “I got a woman” Elvis compared to that of Ray Charles 

2. “That’s all right, momma,” Elvis compared to  “Big Boy” Crudup; plus, “My baby left me” and “So glad you’re mine,” Crudup originals, were also covered and performed by Elvis in a manner that I thought was better than the originals.

Elvis’ versions above (1 + 2) had an integrated spirit, drive, and sensuality that produced a unique sound and generated an exciting, even thrilling listening experience. The only cover he did that was a disappointment to my listening expectations was “Such a night,” which was essentially a note-for-note copy of the arrangement and delivery by Johnny Ray.

"I Put a Spell on You"  Gov't Mule

Feist's version of the Bee Gees' Inside and Out -- very cool.
James Blake's cover of Feist's Limit to Your Love -- WOW -- and a real test for the bottom end of your system!
