Кратко: Synchronize your non-iPod MP3 player with iTune.
iTunes Agent - iTunes is a great music player and organizer. Unfortunately iTunes is made to only synchronize with iPods. Not everyone own an iPod, though Apple certainly would have loved that. How great would it not be if you could synchronize your non-iPod MP3 player, your Playstation Portable and your Walkman phone with your iTunes Library? Enter - iTunes Agent!
iTunes Agent is a tiny application which rests in your system tray, constantly looking for devices being connected to your system. If a device it recognizes is connected it enables you to manage it via a playlist in iTunes. You may even associate your player with a Smart Playlist, such as "Party Shuffle", and always have a new collection of tracks on your player!
When you are done modifying the list of tracks for your player you can synchronize it with two small mouse-clicks!
