Apple iTunes Music: Some Songs Grayed Out & Won't Play

I have a subscription to Apple iTunes Music. On at least one album that I am trying to play from iTunes, not all of the listed "songs" are playable. For example, I am currently looking at the album "The Seduction of Claude Debussy" by Art of Noise. Only the first song/track on the album — "Il pleure (At The Turn Of The Century)" — will play, and all of the other tracks are grayed out and will not play.

This music is streaming from the iTunes Music service and I have not downloaded it to my local device. I have tried this with two of my computers that are authorized to use the account, and I am logged in under the correct account.

I've searched online and I only see references to grayed-out tracks from music that was loaded into iTunes from CD sources... which is NOT the case here.

What is the solution to (or explanation for?) this problem?

Thanks.
