Apple introduced iTunes 8 - the new edition features an updated user interface and has a new feature dubbed Genius:
iTunes 8 includes the new breakthrough Genius feature, which lets you automatically create playlists from songs in your music library that go great together—with just one click. Genius helps music fans rediscover favorite songs in their existing music library and suggests related music on the iTunes Store they might want to add to their music collection. iTunes 8 features new ways of viewing your music and video libraries, and adds television programs in stunning high definition for sale on the iTunes Store.
Using Apple’s breakthrough Genius feature is easy—select any song, click the Genius button, and iTunes instantly creates a playlist of songs that go great together from your own library. You can preview the playlist Genius creates, refresh the list to choose different songs and save Genius playlists to enjoy again later. You can even create Genius Playlists on-the-go with the new iPod® classic, iPod touch, iPod nano and iPhone™. The Genius sidebar appears right in iTunes and recommends music from the iTunes Store that you don’t already have, based on the songs you select.
When you turn on iTunes 8’s new Genius feature, information about your music library is anonymously sent to the iTunes Store, where it is combined with the anonymously-gathered knowledge from millions of other iTunes users and processed through Apple-developed algorithms. The Genius results, specifically tailored to your personal music library, are sent back to your computer to enable users to automatically create Genius playlists in iTunes and on your iPods, even when they are not connected to the Internet.
iTunes 8’s new visual browsing interface displays your music and video libraries using your album and video covers, and also provides a great way to navigate your movies, TV shows, iPhone apps, podcasts and audiobooks.
