I just got a new Mac, and decided to transfer my iTunes library from my old one. One thing led to another, and next thing I know I've accidentally duplicated every single song in my library. Apparently iTunes 11 no longer has a built in feature for finding and deleting dupes (or does it?). I've done some googling, and have found several programs for this kind of thing (Dupin, DupeAway, etc...), but these programs are either ridiculously over-priced (I'm not prepared to spend $25 on some software that I'm only ever going to use once), or simply don't work. Does anyone know of some free software that actually works? Or am I going to have to have to delete each dupe individually? Thanks in advance! PS: Please don't post answers that are relevant only to iTunes 10.
