I play my Apple Music every day and run an app called Song Sergeant. For those who aren't familiar with it, you run it and it finds missing and duplicate Apple Music files every time you run the app. (Actually, you have to do that separate, but that's not the point.) I am wondering, since at the moment, all the songs on my playlist have been played because they either were the first song added or one of accidental duplicates. Do I have to resync my iPod if Song Sergeant finds duplicate files or is it automatic?
