How to get *all* the playlists that contain a given track?

I'm trying to write a plugin to show in the SongContextView all the playlists that contain the selected track. For that, I need to retrieve those playlists for the selected track; how can I do that? The interface com.tamtraug.tunes.Track provides getPlaylist(), but only returns a single playlist.

I see that the contextual menu for tracks has an option for "Show in Playlist...", which opens a submenu with all the playlists. This is exactly the information I need. Is this available from the API?

Or, should I somehow loop through all the existing playlists and check whether each of them contains the song? If so, how can I get the list of existing playlists to start the process?

   In case it matters, my version numbers are:
   macOS 11.6
   Music.app 1.1.6.37
   beaTunes 5.2.24

   Hey there,

   please check out the attached screenshot. You can find out which playlists a track belongs to by using the track's context menu.

   If that does not fit your use case, here's how you get the playlists (in Java):

   import com.tagtraum.audiokern.AudioSong;
   import com.tagtraum.audiokern.PlayList;
   import com.tagtraum.beatunes.BeaTunes;
   import com.tagtraum.beatunes.library.Song;
   import java.util.Collection;
   
   [...]
   
   public Collection<PlayList> create(final BeaTunes beaTunes, final AudioSong audioSong) {
       final Song song = audioSong.getImplementation(Song.class);
       // may or may not be necessary
       beaTunes.getMediaLibrary().fetchCollections(song);
       return song.getPlayLists();
   }
   

   The issue here is that getPlayLists() is not exposed in AudioSong. Perhaps it should.

   Anyhow, hope this helps you,
