This is a 2-disc album from Tidal which I added to my library some time ago but hadn’t yet played. When I selected the album the option ‘Add to library’ was present to my surprise. However, when I selected that option, the album wasn’t found! Yet I can play it!
Odd. Could be a regional thing. I was able to add it directly to my library in Roon. Have you tried going to listen.tidal.com and “favoriting” it there?
BTW, we played this album while trimming our Christmas tree today. Really excellent selection. Thanks for bringing this to my attention. You have great taste in music, @Jan_Wem!
