When looking through the Tragicically Hip's albums, their album called "Phantom Power" is missing. If you know the album's URL, you can browse directly to it, but only the songs that are also availble on their "Yer Favorites" album are available for play. https://play.spotify.com/album/3HWQXn3dGZPSnIhVkvHIOz. This album was available in early June, as I had added it to my library at that time.
Phantom Power is currently available on Apple Music, so it seems hard to believe that the artist chose to remove this one album from Spotify and not Apple Music.
