Unable to buy songs from iTunes

Hello!

There is a specific music album (Pride and Prejudice) that I have bought 1 song from before (off of iTunes), and I wanted to complete the album. But when I go onto the iTunes store, the album doesn't show up. I go onto my Music app and I find the song and when I hit "show complete album", the album shows up as well as the other songs. But it won't allow me to play/buy the other songs unless I sign up for a subscription of Apple Music, which I don't want.

Is there any way to buy songs or buy the album without having to subscribe to Apple Music?

Thanks.
