Thank you I actually love your method. I tried it out, but I also wanted to listen to songs offline, so I actually went and recorded the music using Audacity on my computer.
I hope the dev doesn't mind that I'm doing this. They are putting this game for free so I'm hoping they are cool with it.
I went to check out the other games of the series and the music there is equally epic, and some tracks were even way better.
But anyway, if you want to do what I did here is a full guide although I think most people don't need a guide to do it.
