Right-ciicking a playlist allows me to see "Show in Apple Music". But when I do, I get what I see if I just click – the artwork for the playlist and text under it appears but no track listings. So no workaround for me.
And "Up Next" is not repopulated with the tracks. If I copy the link under "Share" and put it in Safari, I get a web page with all the tracks (and they are clickable and play from within Safari, although off of the actual album the song comes from) but when I click "Listen in Apple Music", I end up with the same page without tracks. So still not a workaround for me.
Clicking on Albums, either left or right, does not bring up anything about "Show in Music". But I can again "Share" and "Copy Link" to open it in Safari and play the tracks. But only from within Safari. Trying to "Listen in Apple Music" simply gets me the circle of doom that never opens anything.
So for me, the only workaround that is not too onerous is to right-click the artwork for either a play list or an album in Apple Music and select "Play Next". This populates the "Up next" Icon to the right of the Track Info in the center at the top of the window. I can then select the track I want to listen to, as well as add them to my library, a playlist or buy it in the iTunes store (click the "..." to the left of the track name). If I like the whole playlist or album, I can again right-click the artwork and chose "Add to Library".
Not an optimal experience but it works for me.
