Is this issue happening at one of the artist pages with the top songs listed on artist pages, or is the issue with some other location on the Spotify apps? Also is the same issue happening with all Spotify apps?
In the list of the music of Carlos Di Sarli appear 55 discs that actually belong to Carlos Gardel. All of Gardel's albums that appear among Carlos Di Sarli's music list are just the ones that appear with a white cover with a dancer dressed in red wearing a hat.
I leave some captures of the discs of Gardel that appear in the list of music of Di Sarli:
Sorry for the late reply, I went through both artist pages and could not see any mixing issues, but boy both artists have a bunch of releases. Anyway I am using a US account, so maybe the content mix up is region specific? If you could provide the Album links in a new post, I can then pass this information along for a Spotify mod to send to the correct content teams to look into. Users are restricted based on listening locations when viewing content, so I do not have the ability to see what you currently are viewing.
