Best cover songs?

What, in your opinion are the best cover songs ever recorded?

My top picks, in no particular order:

Jeff Buckley's "Hallelujah" (Leonard Cohen)
Dar Williams' "Comfortably Numb" (Pink FLoyd)
Matt Nathanson's "Romeo and Juliet" (Dire Straits)
R.E.M.'s "Dream" (Everly Brothers)
Jimi Hendrix' "All Along the Watchtower" (Bob Dylan)
Johnny Cash's "Hurt" (Nine Inch Nails)
The Beatles' "Twist and Shout" (Top Notes)
The Cowboy Junkies' "Sweet Jane" (Lou Reed)
The Sundays' "Wild Horses" (Rolling Stones)
Mindy Smith's "Jolene" (Dolly Parton)
Rickie Lee Jones - Marty Balin's "Comin' Back To Me"
Matthew Sweet & Susannah Hoffs - BeeGees "Run To Me"
Eva Cassidy - "What a Wonderful World"
Sarah McLachlan - Tom Waits' "Ole 55"
Victor Wooten's version of Naima by John Coltrane. Available on his album titled "What Did He Say". Incredible Bass and acoustic Guitar, etc.
Dylans I Was Young When I Left Home by Antony Hagerty and Bryce Dessner (National)from the Dark Was The Night compilation. Antony and the Johnsons also do a beautiful Knockin On Heavens Door on the I'm Not There soundtrack. If you have not heard that soundtrack I highly recommend it.
