listening to all the unused Doom music by Bobby Prince and a lot of it is ... quite literally just... friggin midi covers of existing songs hahaha
like, there's a lotta alice in chains stuff. Like, Barrels O' Fun from Doom 2 was just... VEEERYYY similar to AIC's "Dem Bones", but one of the unused tracks is ... literally just Dem Bones. verbatim. not even TRYING to disguise it hahaha.
