Thousands of duplicate songs on music app on iPhone but no duplicates on Mac
I have an extensive music library originally created in iTunes by uploading my CD collection and later moved to Apple Music. I mainly play music from my iPhone and at some point I noticed that there were duplicate tracks. In an album there may be anything from 1 or 2 to every track duplicated. Anecdotally, the tracks that I have rated and/or favorited are more likely to be duplicated.
I have removed some duplicates on my iPhone my manually removing individual tracks.
When I recently looked at the same albums in the music app on my MacBook, there were no duplicates on albums that still have duplicates on iPhone. However, some albums that I de-duped on my iPhone now have missing tracks on my Mac!
Btw, I ran the duplicate detection on my Mac and there are no duplicates detected there. But I still have thousands of duplicates on my phone, and now missing tracks on my Mac. It's a complete mess.
Please don't send me a link to the standard duplicate removal FAQ.
