Extended information
Genius playlist

Synchronization function
Synchronize iPod with other players
1. Whenever an iPod is connected to it, iTunes will automatically synchronize its music and videos Library (the OS X version of iTunes can sync several different digital audio players; the Windows version of iTunes only supports iPods).
2. New tracks and playlists are automatically copied to the iPod, and tracks deleted from the computer music library will also be deleted from the iPod. The ratings of the track in the iPod will be fed back to the iTunes music library, and the audiobook will remember the last played position.
3. Auto-sync can be turned off to allow manual copying of individual tracks or complete playlists; however, iTunes can only copy music to iPod but not the reverse, which inspired third-party software Supports copying music from iPod. Through some software, this work can also be done on the Unix command line.
4. When the iPod connected to the computer does not have enough remaining space to synchronize the music library in iTunes, a playlist with the same name as the connected iPod will be created. This playlist can be changed by the user to fill the available space.
