You can download the stems for "O.N.E." over at the Mad Decent website. Rework the track, put it up on the site and then they will all be available to the public for voting and (hopefully) consumption. It all closes May 14th. One grand prize winner gets a Native Instruments Traktor Scratch Pro, Yeasayer's Odd Blood on CD and LP, and your remix featured on the Mad Decent website. Four runners-up get the Odd Blood CD and LP, a Yeasayer t-shirt, and Beats Earbuds.
If you're submitting a remix, and you think I'd like it, send it over to me via email and you might see it on the site.
