iTunes 3.0.0

With millions of copies in circulation according to Apple, iTunes is easily the most successful iApp to date. Because it was one of the first iApps introduced, Apple has had a long time to apply the necessary polish to make iTunes look good and work well. And it shows. iTunes has come a long way from that first release and is coming close to an "excellent" rating.
Like previous releases, iTunes 3 is more evolutionary than revolutionary, so dont expect any dramatic changes. Indeed, many people will probably feel that this is iTunes 2.5 at best. Nevertheless, iTunes started with a solid idea and there is nothing wrong with simply improving on that concept. In fact, iTunes is the currently the best MP3 player available for OS X.
The new main features in iTunes 3 are:
Smart playlists
Support for audio books from Audible.com
Sound check
Track ratings
New tags for play count, last-played date, and composer
Library consolidation, including compilation flag
Playlist import and export
Ability to join tracks
