Whenever im in a different biome or time, no music plays. I already tried to solve the problem myself but i couldnt find anything. Never heard a music after i installed this mod.

Make sure your music volume is not at 0, Make sure you dont have any resourcepacks stopping the game from playing music. make sure youre waiting long enough for music to start. If youre impatient for music to play, try installing music duration reducer. If none of those work then tell me what mods you have installed and resourcepacks.
