My god, have I butchered the song "Rainbow Factory" a lot. I can assure you that this is DEFINITELY my final version.
"Rainbow Factory" is part 1 in this two-part song. It describes what goes on in the factory, which would be killing Pegasi to collect their Spectra, or pure color. In "Awoken," part 2 of this song, one of the employees at the Factory has an epiphany, and tries to redeem himself to the real world.
