Best way, I think, is to export a scripting interface so that every time a song is indexed, the script has a chance to edit the tags based on info like file path, etc.
That’s probably nearer term than UPnP. I hope in the next week (I have the week off) to start on the scripting interface. We’ll see how far it gets.
Yeah thanks really for your answer. I’m not sure if I understand that completely :D, but thanks indeed for your generous works!
