Johannes Kreidler's "Product Placement" (above) a 33-second remix that uses 70,200 samples to create a glitch-heavy masterpiece. (I'm not sure what the criteria are for "masterpiece" in this genre, but Kreidler's clip makes Girl Talk seem like lazy muzak.) Create Digital Music has some background as well as a video of the phone call he made in his attempts to clear copyright for the samples for his work (the licensing agency requires an individual request form to be completed for each sample).
