Today Apple demoed a brand new version of iTunes for Mac and PC. 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.

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.
