PowerTunes helps you manage multiple iTunes libraries.You can copy music back and forth between libraries, for example, while maintaining ratings, play counts and other information. You can also fix dead tracks whose files have gone missing and find "orphaned" music files.

PowerTunes requires Mac OS X 10.4.9 or later and iTunes 7.0 or later.
