The mod works fine on it's own, however when I load the mod with another animation mod named 'Epic Fight', the animations for playing music don't work. Instead, my character stands still and all that appears is the music notes and the music still plays.

As it does not completely crash the game, I will still use both, however it would be nice to have this bug fixed.

No, I will not add support for Epic Fight. Way too much work. I recommend using a mod which does not replace the player.

I know it isn't exactly a perfect fix, but you could use filterAnimations: True to make the playing anims work outside of combat mode
