I like the changes you made it makes things have a better fitting theme
the otherworldly underground ice biome music has always seemed too dark for the biome it represents and it being in the underground corruption makes much more sense I know re logic had to repurposed the songs to make the songs available but this maches so much more and creates a mod that makes both soundtracks combine in a way i enjoy as it makes some of the bosses and biomes have their own themes

only one a lil bit weird is the underground hallow as the blood moon music but I cant really think of anything better so don't take that to harsh i still like this mod

you have mad good mods and I plan to check out more of them you don't deserve the criticism you get and i hope you continue to create more for this community
