Best Cover Song Ever?

A reader recommends an extreme genre-bender:

Great contest. Let me nominate an unconventional, but brilliant, submission by Girl Talk. You want genre mixing?  How about something that includes parts of Black Sabbath, Ludacris, Dorrough, the Ramones and Missy Elliot, among others (plus equally amazing video):

Is it a traditional cover song? No, but if this is the future of the cover song, we are in extremely good hands …

Previous coverage of the Dish’s favorite mashup DJ here. Another reader:

I can’t be the first to submit Cowboy Junkies covering Lou Reed’s “Sweet Jane”. This version is so good Reed himself changed the way he performed the song live:

Another:

How could I forget this one?!  Another example of the cover being better than the original. This time it’s Sheryl Crow covering Cat Stevens’ “The First Cut is the Deepest”:

Another:

Please consider the Fine Young Cannibal’s cover of “Suspicious Minds”. Both Elvis and FYC had a hit with this one:

Check out all the nominees here. Update from a reader:

Might I advocate for keeping the covers contest limited to “clean” covers and saving mashups for, possibly, a later contest? You’ll be hard pressed to beat Girl Talk at his own game, but you’ve got stuff like Pogo (with gardyn being among my faves there, and this boosh remix) competing for the “repurposed splicing” title (though let’s be honest. Girl Talk is in a league of his own with the breadth and depth of his mashups). Hell, you could have individual Girl Talk and Pogo contests (I would put “Minute by Minute” up against “Oh No” for Girl Talk)

But then beyond that, you’ve got other more focused, less all-over-the-place mashups:

DJ Danger Mouse’s Grey Album (Jay-Z’s Black Album vs. the Beatles’ White Album) [probably the gold standard as an album, but individual tracks out there can at least compete]
Sham Sham’s 99 Hearts (Jay-Z’s 99 Problems v. Architecture in Helsinki’s Heart It Races)
Psycosis’ In da G4 Over the Sea (Neutral Milk Hotel vs. various rappers)
Amerigo Gazaway’s Yasiin Gaye (Mos Def [Yasiin Bey] vs. Marvin Gaye)
the Notorious XX, Wait What (Notorious B.I.G v. the XX)

I find all of these, in their own way, to be amazing examples of how someone can make something completely new out of two songs that seem wildly different. Or maybe I’m just hoping you’ll crowdsource my efforts to find more mashups like this.
