Music Choices by Tmtravlr

Lets you change the music that plays in different dimensions and biomes, including modded ones. Also lets you play music in the menu. Put the music files in a folder 'MusicChoices' in the config file, in the folder with the number corresponding to the dimension ID (for example, the folder '-1' for the Nether), the 'Menu' folder for menu music, or the folder in one of the 'Biomes' or 'Biome Types' folders with the name of the biome / biome type you want them to play in.
