Removing the duplicated tracks is a pretty straightforward process, and you can see how to do this on the Apple support site. It does become a problem when you have a really large library though, and let's face it, who doesn't? The effort involved increases with the number of tracks, and basically becomes an pain in the backside. A serious pain. I did some research into the problem to see if there is an easy way around this. There are a number of 'scripts' provided by programmers, but these are Mac specific and require some technical knowledge to use.
I've come to the conclusion that the only way to do this correctly is a software package that automates the entire process. Software cleans your music library, doesn't require much input from you, and gets the job done. These products clear duplicates, fixes missing track and genre info, and updates your missing cover art, all automatically. If you run this every week, your library will be maintained properly, without you needing to do any of the work. Thousands of users and music lovers with large libraries are already using this, as it's the best way to keep your music collection clean.
