Thanks! That is very cool. However with this approach I am missing two functions. First, I am using the catalog relationship using the "include" parameter to get the catalog identifier of the library artists. Is this possible with this approach, given that the Artists in the MusicItemCollection have the library identifier? I am using the catalog identifier to make a custom request to get the latest "X" amount of albums (sorted by releaseDate) directly from the API Endpoint. If I can load a collection of latest albums (instead of the lastestAlbums property), then I might not need the catalog identifier in the first place.
