Yep, "Pink Martini - A Retrospective" was removed after I bought one song from it, when I click on the track in my library the error toast states "It's impossible to play this track. Thank you for trying another playback format."

But that's the whole point of buying it, mp3 is safely on my SD card, plays just fine

> Qobuz removed a range of releases a couple months ago at short notice, including from users' accounts.

What was the deal with this?

It wasn't explained officially. I assume some distribution arrangement changed but the artists/releases were so varied and from various labels that I can't determine the relationship. I'd bought a handful of releases there and all of them were affected.
