Apple has released version 3 of iTunes, their awesome, free digital music jukebox application.

Among the nifty new features are “Smart Playlists,” playlists that automatically and dynamically update their songs based on user-defined rules.

iTunes 3 also sports a new song rating feature that you can use to rate songs and if desired, add them to a smart playlist.

Since playlists are the method of transferring songs to the iPod, Smart Playlists will make updating the iPod more dynamic and automatic. New songs by an artist or genre specified in a smart playlist will automatically be added to that list and thus to the iPod.

Other neat features are: “Sound Check,” which will automatically adjust output volume to maintain consistent levels; support for content from Audible.com; support for new .mp3 tags that keep track of playback dates and counts; improved control over music file and folder naming and storage; and a purty new purple dock icon.

What’s your favorite new feature in iTunes 3?
