What is your favorite cover?

And to follow up on @bigtwin 's comment, it is interesting to consider what makes a good cover. So much of music history had a separation of composer and performer. I always think of a good cover as one I want to listen to as much or more than the original. Sometimes a new performance shows something else magical about the composition itself that the original doesn't capture for lots of reasons. Thanks again to the OP for generating this offering of performances!

Eddy Vetter singing "Masters Of War."

Johnny Cash "Hurt"

Disturbed "Sound of Silence"

Leonid & Friends doing any of Chicago's catalogue. Check them out on youtube - out - frickin - standing!!!  All songs note for note identical & perfect even though they may not even really know what the songs mean. Funny. They're all Russians but simply great artist citizens - nothing to do w/ crazy man Putin.
