In summary, only menu music plays in the menu, biome-specific Nether tracks have a 2x chance of playing instead of 7x, 1.20/Aaron Cherof tracks have the same chance of playing as the older tracks, and most overworld biomes no longer favor songs. (Unchanged from vanilla: Lush Caves favor Left to Bloom, Meadow favors One More Day, Old Growth Taiga favors C418's tracks, Stony Peaks favors Stand Tall, Swamps still exclusively plays Aerie, Firebugs and Labyrinthine, and Underwater still strictly plays Axolotl, Dragon Fish, and Shunji).
