Work music won't ..well...work. in a music mod.

[Naughtyfin]

I have been working on a mod, that changes the Music from don't starve.
Everything seemed to be working until i started the game, where i realized that the Music that supposed to be playing when you're working won't start.

Yet Danger and Epicfight music seems to be working fine. i dont know what to do.

i used this tutorial for modding. i also saw that some of the work files seem to^have a b at the end. like Workb while others where just normal.

this would be the mod.
Could somebody help me please?
