Yeah, that's not a complete script - I would have described it as a skeleton, rather than flesh, but that is an unfortunate instance of terminology. The point is, that script is meant as something to help another scripter coming along who would want to make a jukebox. It does nothing as it is. If I remember, all it does is create a class for collecting and calling BGM data necessary for a radio script - a scripter would still need to make the windows, scene, and most everything else before it could be a working script.
