Kutiman-Thru-you - 01 - Mother of All Funk Chords
This guy created an song entirely by stitching together unrelated youtube video clips of individual people playing single instruments.
This is not only a great idea, but the song is actually really damned good. Consider me completely blown away speechless.
(As of now, this has 79,547 views... it will be fun to watch over the next week to see how much this video explodes...)
