Duplicate songs on iPhone 12 mini, no dupes on Mac
Macbook Air M2, 2022
Ventura 13.2.1
iPhone 12 mini iOs 16.1.2
I've ended up with duplicate songs on my iPhone, but not on my Macbook Air.
Music is taking up 56.79 GB on phone and only 29.91 GB on Macbook. Albums themselves do not appear to be duplicated. Instead, each album has two copies of every song. 1, 1, 2, 2, 3, 3...
This appears to be happening on albums that I own on CD and have put on to my Mac and then synced with my phone. Albums that I purchased and downloaded through iTunes/Music do not seem to have duplicate songs.
So, how to de-dupe phone when the dupes don't appear on my Macbook Air?
Thanks for any advice.
