Easily add fully functional background music to Unity!
The BGM Manager singleton is a simple and complete solution that offers a per-scene music controller for Unity. With this each scene is now capable of randomly selecting a musical track at load-time. It also allows for the music to be muted, unmuted, overwritten or have its volume modified all in a single line of code. This is all achieved using two classes, a singleton controller and a per-scene data container.
You can find it on the Unity Asset Store.
