Mother of all Funk Chords

This video is awesome. And brings up massive copyright issues. If remixing lots of instrumental solos into a brilliant piece of music is wrong, then it stops people from doing amazing new, creative works of art. Yes, the artists who were remixed were infringed, but any reasonable theory of copyright can't possibly see this work as diminishing the market for their performances. I would have never watched any of them before, but now I'm curious to see the individual parts that fed into the whole, even unwittingly.
