Get the error “This song might not be available in your country or region”

Noticing some songs in my Apple Music library will no longer play due to this error when streaming to my mobile devices but will play just fine from my local device because I have a copy of the actual sound file on my Mac. If I browse Apple Music or the iTunes Store I no longer see the album or related songs which I guess explain why they won’t stream? Bummer because I swore they were streaming just fine a few months weeks ago. So this is a dynamic, ongoing situation we have to deal with when streaming our libraries? Unless the song is listed on US Apple Music or iTunes store it won’t stream? I don’t remember this being an issue with iCloud Match? 😕
