The soundtrack is 49 minutes long and has been completely remastered by Kyle Gabler. The 2D Boy servers have been bombarded with traffic, so much so that a mirror has been created to help with the increased traffic. If you hit a dead end, keep trying as the traffic will eventually die down enough for everyone to get the soundtrack.
We'd like to take a moment to thank Kyle and the rest of 2D Boy for making this amazing soundtrack available for all. It's easily one of the best video game musical offerings of last year.
