This has occured a handful of times in the past, but has gotten a bit intrusive lately. This appears to occur with random artists and at random intervals. Using Firefox 91, but the issue has occured on chromium 102 as well.
Thanks @gassug2 . I’ve been working to track this down. About a month ago, we integrated the TasteDive recommendation API to fetch related artists and use this to help with the “suggestions” collection on the song page. But the API isn’t as robust as we had hoped and sometimes returns some strange results. I’ve been adding error checking trying to improve this. If you see this in the future, please post a link to the affected song page b/c it helps me debug.
