The Album Artist field when talking about musical metadata is the artist under which a particular release is classified under. Artist is the people that are on a specific track, including thing like featurings, etc. Here we only want to set Artist (the most generic item). Album Artist overrides artist, and has nothing to do with the album name. Windows doesn't have an API or a location in the UI to display the album name.
