Using Dynamic surroundings version1.16.4-4.0.1.4

Forge 35.1.10

The actual Forge version - "latest" does not count.

Battle music cannot be configured to play as there is no configuration option for such a thing within the mod or the config file.
Please fix this, battle music was the sole reason I installed this pack.

Yep - was removed. Reason is that the mod is 100% client side. For battle music to work it would need to be installed server side. I may create in a separate mod.
