This is a comments thread for the following album: https://downloads.khinsider.com/game-soundtracks/album/crack-down-gain-ground
I believe these might be tracks from the Arcade version, which didn't have a round 4 (or rather, the Genesis' round 5 is the round 4 of the Arcade version). Both versions sound very similar so that's most likely the case.You totally skipped Round 4 of Gain Ground; number 13 is actually Round 5. Otherwise, good music
