SNL Spotify Playlist of every song played on the show(plus favorite all time performances)

I had seen that somebody else had gone through the trouble of doing this, but now SNL has officially put it out there: http://open.spotify.com/user/nbcsnl

This got me thinking, what are some of your all time favorite musical performances from the show? I'll start it off with two:

Paul Westerberg "Can't Hardly Wait"

The Replacements had been banned for being drunk and rowdy during their appearance in 86'. Paul Westerberg came back in 93' and dropped this amazing version of Can't Hardly Wait. Notice the drummer and watch Paul laugh when somebody shouts out "Burt Reynolds!"

U2 "Elevation"
U2's first appearance didn't come until like 20 years into their career. Elevation isn't a great song, but this performance always stuck with me because of Bono being the first singer I'd seen to get off the music stage and get the crowd into the show. Plus he references Lennon and does a little Jim Morrison for Val Kilmer.
