I bet you could release it later as a regular album with some in universe lore about a video game/film that was held back from development for some reason, and have it be one of those albums that does cool worldbuilding. That would go hard
I'm now working on an album for one of my favorite things to compose music for, which for now I can say is a Minecraft Mod, although the soundtracks I make I doubt would get into the Minecraft Mod Itself. However, maybe there's a chance that if the album I'm working on right now can get into the Mod, it may come in the form of an Music Addon Mod.
