Hi, I started with a new application, but I struggle with setting up my Models and Relations. Let me give you a quick idea of my project:

I have 3 Models: User, Playlist and Radio. I want Users to select radio stations from a predefined list of stations and add them to their playlists. A User has playlists and these playlists have radio stations. But the User isn't the actual owner of the radio station.

So my question is: How do I handle the removal of a station for example? What if a User wants to delete a station from his playlist? Or the other way arround: How can I associate a station with a user/playlist?

I know this question sounds weird, but thats because I can't really find the right words to describe my problem.

I hope you will understand :)
