Hello, everyone! I hope this message finds you well!
This problem is difficult to search for an answer for, because most people assume I'm talking about duplicates of the same file that's located on the computer. That's not what I'm looking for. I have a large playlist where many of the songs were errorously added twice. And I wish to remove them. For some reason the "Duplicate track detected - do you want to add the track to this playlist?" confirmation prompt didn't work and some entries were added anyway. This means the Tools>Manage Duplicates (although an incredibly useful and powerful tool) will not work in this situation.
Is there a way I can remove these double entries automatically?
