It probably depends on the license the song was distributed under. Asking the people/person you purchased it from is likely the easiest way to find out.
This game looks epic, especially for indie game dev. Pay pal is easy to set up, fast, and (above all else) safe! Make an account if you like this game and BUY IT!
I've been an aspiring game developer for a long time; but I've also been unsure about when I have enough skill to join a game jam. I think you just inspired me to get out there. Chase the dream! Thank you for the inspiration!
