Filter Apple Music Playlist by Zero Plays

Hey there,

I would like to create an apple music playlist and then filter that playlist by playcount = 0 to create a playlist of songs I have not listened to. I am bumping up against the 100k song limit, so the songs on this playlist are not added to my library.

Create the playlist, add songs to it but not to library, create smart playlist w/ filter, but then smart playlist is not showing zero play songs from parent playlist.

Are plays tracked on songs not in your library?

Am I missing something else?

Thanks.
