Removing Duplicates from iPod
I have an iPod touch, 6th edition.
Currently I have a large number of songs that are duplicated on my iPod -- entire albums where every song appears twice, making playing through the album awkward. Curiously, these tracks are NOT duplicated in my iTunes library that syncs with the iPod -- only on the iPod itself. Because of this, the "detect duplicates" in iTunes does not help me.
Is there a way to make the iPod recognize the duplicate songs and either automatically delete one copy of each to match my iTunes library, or at least list them directly so I don't have to go through my entire library album by album trying to figure out which are duplicated?
