It would be helpful to know what device you are running Village Sim on (Palm, Clie, etc.) and whether you installed it in main memory or on an expansion card. However, there are a few general things you can check to make sure that it's not something simple.
The first thing to check is to make sure that you loaded at least one of the music files when you installed the game. They are not automatically installed when you install Village Sim. Also, make sure that the music isn't turned off in the Village Sim game preferences.
If you are running Zlauncher, you should try putting the music files in internal RAM, if you run the game off the card through ZLauncher. (Some of the beta testers discovered this during testing.)
If none of that helps, please provide additional information about your device and how you installed Village Sim, and we'll help you figure it out.
