I haven't given A-Trak's Nike+: Original Run record any serious thought, but I've heard considerably good things. I remember catching him play in Chicago a few years back, right after he quit hiding behind Kanye's shadow. Nowadays, he has deals left and right, a talented girlfriend, and now this (which takes the cake): a Serato vinyl disk commemorated just in time for his Nike gig, thanks to the boys at Whitelabel.net. It's a work of art. And I'm buying one. But hold on--only 1,000 are being pressed. So get if I were you, I'd get one soon, too.
Whitelabel.net is also great for getting exclusive tracks, in case you wanted an alternative to iTunes.
Oh, and you can purchase A-Trak's Nike+: Original Run album right here.
