Until someone releases the proper soundtrack, here is a game rip of it. Three of the songs ("The Genki Star", "The Section Lords" and "The Core") had voiceovers mixed into the song tracks and I couldn't find anything in the sound files that were just the music only, but everything else is just the songs only. As an added bonus, I added the individual song layers for some of the songs so you can hear different versions of the songs without them being blended together.
