Q: I have 5,000 duplicate in iTunes. How is the best way to delete them?

Hey infantryman,

Thanks for using the Apple Support Communities! I know that it's important to be able to easily manage your iTunes library, so I'm happy to give you some assistance with these duplicate tracks.

Luckily, iTunes has made it very easy to manage duplicates, which I'm sure is especially useful with over 5,000 items! You can see more about this here:
