Since the app does not prevent or notify you that you are adding duplicates to a music playlist, I’d like to clean it up and search for duplicates. How can I export the playlist to a searchable format like a text file? Are there any third party apps to identify songs I’ve added twice?
You cannot add the same track twice to a playlist. Adding it the second time will be silently ignored.
If you are adding the same title in a different version/recording/album – sorry, that won’t get detected in all cases.
