music issues

I think this should help if the problem remains:

Open the Terminal (in Applications/Utilities) and type:
touch /Applications/Penumbra\ Collection/Black\ Plague/maps/*.node
then hit enter and you can close the Terminal.

Then try running the game from start and see if that helps. The above "touches" all the enemy navigation files, which changes their modify date, which I hope will make the game think that the files are new enough and not try and re-create them.
