MusicKit album.isCompilation -- al… | Apple Developer Forums

I can not find an album where isCompilation is true, even when the album clearly consists of "songs by various artists". For example:

 Album(
  id: "567979803",
  title: "Earth's Answer",
  artistName: "Brian Keane, Deuter, James Newton, ,...many more",
  isCompilation: false

The compilation checkbox for this album in the Apple Music Catalog Get Info dialog is also not checked.

Is this field NEVER SET in the catalog or the MusicKit API?

If there IS an album where isCompilation is true, I'd like its ID to use for a test case. If not, can this be added to the API?

MusicKit album.isCompilation -- always false?
