I saw this video the other night and man it was pretty impressive. Madeon had an idea and started playing around with it and did a mashup of 39 different songs to make one sick mashup. It would have been interesting though to see the software side of the setup before mixing it up but you take what you can get. This 16 year old producer from France has some skills that I can only image will get better. After checking out this video check out some of his other remixes as well.
