Apple Music seems to be experiencing a bug that causes other users’ playlists to show up in random users’ libraries.

First spotted by MacRumors and AppleInsider, there are a number of Reddit threads from impacted users. Users are reporting strange playlists showing up in their libraries.

“So I went to ‘listen now’ > profile > edit profile,” wrote a Reddit user named CripplingToaster, “and scroll down to shared playlists and I see it only shows my original playlists and not the ones that randomly popped up, so I feel like it could be a glitch with the server?”

Apple has so far not responded to inquiries from either MacRumors or AppleInsider, and it’s unclear what is causing the problem. Apple’s silence is especially concerning given that these issues have been happening for nearly a month.
