Add extra music/songs to the game...

Hi there;

It may have been written down before but I could'n find that tread.

I want to add music to the different ages in the game.
Does anyone know how to do that.
IE, which files do I have to change to make that work after copying the files to the specific folders.

Thanks.

Assets (or CustomAssets)/Sounds/Soundtrack

Place in the appropriate era folder.
