I very often come across the issue of a single artist - in the example below Brigit Nilsson - showing up in various combinations with other artists. Upon opening these faulty links it shows that these are coming from albums in Qobuz not properly tagged: The Artists Birgit Nilsson, Jussi Björling, Renata Tebaldi etc. are all joined together in one artist tag.
This is obviously incorrect and not an isolated case but pretty common. If you wish, I will post more screenshots.
I would be grateful if you could take up this issue with your friends over at Qobuz.
