“Restoring” music from the demo version of Fur Fighters

[MetroLSD]

By “Restore” I mean modding the game to replace the music in the game’s second world with the one used in the multiplayer of the world 2 map,The demo version of Fur Fighters found on Generator Vol 2 has a level from the second world (the dam) which is mostly the same as the final version, However the biggest change is the music, in the final version each world has a theme song that remixed with different instrumentation and tempo depending on which of the 6 playable characters the player is controlling.

Meanwhile, The normal world themes are never heard in the single player the game, instead they can only be heard in the multiplayer mode versions of their respective worlds, this includes the demo version of the world 2 theme which in the final game is used in multiplayer.

TLDR,The music used for world 2 in the demo was instead used in multiplayer in the final version of the game,Could someone look into making a mod, or romhack of the game that changes this back?
