title: How to get the playlist of currently playing item using systemMusicPlayer?
body: <p>I'm currently building a music app and I want to get the playlist of the currently playing item (in Apple Music). </p>
  
  <p>I don't mean I want to use a MPMediaPickerController, because I only want to get the media items of the current playlist.</p>
  
  <p>Thank you very much for your help!</p>
