I did some more digging and the official release date for the promo vinyl was Dec 24/07, which is confusing because S&L came out in may of that year. Im guessing it was out unofficially before the album dropped and once it didnt make the cut they released the vinyl to recoup a bit of the money put in to pushing the single. The fact that Play N Skillz did the beat and all the previous work they had done with bone was in late 05 and early 06 when they were doing some work with Chamillionaire makes me think (and im just speculating) that this is from those sessions.
