Brilliant!

I actually was looking at creating a web site for just this sort of thing - audio only, however. It was to be called "rottenguitar". People would upload their rotten guitar playing and others could vote on the worst examples (who is the rottenest of all?). The site would sell ads for guitar stuff and such.

In any case, when I talked to a lawyer about it he said I'd probably get sued because people don't want to hear just any rotten guitar, but rotten versions of songs they know...

Bleah. I do have a couple of examples of (my) rotten playing on rotten originals here: http://rottenguitar.googlepages.com/home
