Apple's newly redesigned iTunes has finally been released after a one-month delay, for both Mac and PC. iTunes 11 sports a bevy of new music features, including a streamlined look and feel that focuses on album art when listening to music, a new bite-sized MiniPlayer, a new feature called "Up Next" that lets you manage a play queue. Outside of music, iTunes 11 brings tighter integration with iCloud, allowing you to stream your content library on your Mac or PC from iTunes in the Cloud. The iTunes Store has also been completely revamped, bringing the same look and feel that you'll find in iOS 6.
You can grab iTunes 11 now by running Software Update on your Mac or PC, or by checking the Mac App Store.
