intoart, you reminded me of this classic clip of William Shatner doing Elton John's Rocket Man.. I'm not sure if this is the best cover song ever or the worst..

YouTube - Bill Shatner

Curt Cobain's cover of the Meat Puppets' "Lake of Fire?

Red Hot Chili Peppers - Castles Made of Sand (Orig. Hendrix)
Counting Crows - Friend of the Devil (Orig. Grateful Dead)
Staind - Comfortably Numb (I shouldn't even have to say who wrote that.)

Metallica - Am I Evil?

That Biz Markie clip was strange yet inspired performance.

x4 (I think) for Jeff Buckley's performance of Leonard Cohen's Hallelujah

Someone mentioned it before so I'm only agreeing with this one...
Johnny Cash - Hurt (NIN cover).

Someone also mentioned Along the Watchtower, Hendrix covering Dyland, but I'll add Dave Matthews cover to it as well.

Lastly my favorite...
Fiona Apple - Across the Universe (Beatles Cover).

I'm a diehard beatles fan and it sounds like blasphemy that anyone could one-up them but her cover of that sound is just incredible. Especially how her voice is so monotone and sloooow. Hard to explain but I just love it.

I like Death Cab for Cutie's cover of The Smith's "This Charming Man."

Also Orgy's cover of New Order's "Blue Monday."
