Cornbreads Music Fixer v Trails and Tails Update

For all the lovers of C418's classic soundtrack, or maybe just the people that are mildly annoyed that Mojang keeps making music play in places it's obviously not supposed to (swamp music plays practically everywhere in vanilla), this pack reworks music so that old biomes don't play music that isn't written for them! Also, makes loud music quieter, and rebalances Nether Music so that C418's tracks play more often.
