The OST to a relatively unknown game called 5089 is actually pretty good. It's cheap on Steam but you have to search the game files a bit to actually find the music. I found the soundtrack in: Steam\steamapps\common\5089\lib : in a .jar file called assets. Using WinRar or something should allow you to extract the music out of the: Sounds\Music : folder. I haven't found the soundtrack anywhere else on the Internet.
