Have you ever wanted to sync two different music libraries or compare yours with your friends? Doing it manually is a waste of time. These 2 music library comparison apps can make your life easy:
Synchronicity: this iOS app lets you compare music libraries via WiFi or iMessage. It displays color-coded results, so you can easily see which songs, albums, and artists you have in common.
