Q: How to solve the "music playing at spawn" problem

You probably had Dynamic Surroundings installed. Don't worry, it isn't a total necessity to outright prune the mod off your modlist. Instead, you may follow these steps to resolve the issue while still keeping Dynamic Surroundings around - fingers crossed! https://docs.google.com/document/d/1T0fpHUYm9zE_luBFx0mNjUFQxZxxc6drXSR_lBbBJCc/edit?usp=sharing

About Boss Music Mod/Datapack

From Modrinth

This mod adds music that will play during epic frays against both the Wither and the Ender Dragon.

𝔹𝕠𝕤𝕤 𝕄𝕦𝕤𝕚𝕔 𝕄𝕠𝕕

This is a mod/datapack with a focus on incorporating music to accompany the player during brash encounters with both the Wither and the Ender Dragon. That's about it, honestly.

You may adjust the volume of the music in the mod via the "Jukebox/Note Blocks" slider in Options > "Music & Sounds" in the menu in-game.

You can also run two different commands that toggle the mod's boss themes.

_/trigger bmm.wither_theme.toggle_ to toggle the Wither's boss theme
_/trigger bmm.ender_dragon_theme.toggle_ to toggle the Ender Dragon's boss theme

Music featured within the mod:

84tangelo - The Wither (Theme of the Wither)

solunary - The "End" At Hand (Theme of the Ender Dragon)
