Weezer's cover of Earth Angel (The Penguins) is AMAZING... you can tell the lead singer LOVED this song... so pretty ;)

How about the two Meat Puppets songs that Nirvana covered in their unplugged sessions on MTV...

"Lake of Fire"

"Plateau"

Also I like the Incubus cover of Big Punisher...

Incubus - Still Not A Player (Big Pun Cover)

"Smells like Teen Spirit" by Tori Amos

Cruisin' - D'Angelo

Drift Away - Uncle Kracker

Behind Blue Eyes - Limp Bizkit

American Woman - Lenny Kravitz

An interesting note (to me anyway): just heard on Sirius 16 (The Vault) that the Flying Burrito Bros version of "Wild Horses" was the original, having been recorded 1 year prior to the Stones. Jagger & Richards wrote it and gave it to Gram Parsons to record and then THEY covered it.

tori amos' "i'm on fire"...does the boss well. :)

I just heard "You've Got to Hide Your Love Away" by Eddie Vedder (Originally The Beatles) from the I Am Sam soundtrack. Very good cover, true to the original, but in Vedders unique style.
