I'm currently working on integrating MusicKit into my app and would like to provide a seamless user experience by displaying only the songs that are available in the user's region or country. However, after going through the MusicKit documentation, I couldn't find a direct method to determine song availability based on the user's location. I wanted to inquire if there is a way to determine if a specific song or a catalog of songs is available in the user's region or country using MusicKit. It would be incredibly helpful if someone could guide me on how to achieve this or provide any insights on alternative approaches. Thank you in advance for your assistance!

Dear Apple Engineers, I would like to make a request for an extra flag within the Playlist struct. This flag would serve to indicate whether the artwork my app receives for a playlist is a custom image uploaded by the user or a standard 4-image collage consisting of the first 4 songs. The purpose of this flag is to enable us to display a filter in the table view of our app, specifically showing playlists that do not have a custom user image. Thank you for your attention to this matter.
