iTunes is a free application for your Mac or PC. It lets you organize and play digital music and video on your computer. It can automatically download new music, app, and book purchases across all your devices and computers. And it’s a store that has everything you need to be entertained. Anywhere. Anytime.

What's new in iTunes:

As part of iCloud, iTunes in the Cloud takes what you buy on iTunes on one device and pushes it to all your other devices, wirelessly and without syncing. With iTunes Match, even the songs you’ve imported from CDs are stored in iCloud — so you can access them on your iPhone, iPad, iPod touch, Apple TV, Mac, or PC. And the iTunes Store now features thousands of movies and TV shows in stunning 1080p HD.

1080p movies and TV shows
A new definition of great entertainment. The iTunes Store now features thousands of current and classic movies and TV episodes in stunning 1080p HD. Rent or buy the hottest HD movies and buy your favorite TV shows and start enjoying them in moments. The iTunes Store automatically downloads the highest-resolution video your device will support, so you’ll always see the best possible picture.1 And with iCloud, you can start watching those movies and TV shows on one device and finish them on another.

Buy here. Automatically get it everywhere
With iTunes in the Cloud, the music you download to one device automatically appears on all your devices. So the song you buy from your Mac at work is ready and waiting for you on your iPhone when it’s time to drive home. Regardless of where you click or tap Buy, iTunes will automatically download your new songs, apps, and books to your other devices over Wi-Fi or a cellular network.

Individually download past purchases
When you buy a song, movie, TV show, app, or book from the App Store or the iTunes Store, iCloud stores it in your purchase history. So you can download what you want, from any of your devices, to whichever devices you choose.2 For example, if you don’t want your iPad to automatically download everything you buy on your iPhone, you can choose just the things you do want to download — song by song, movie by movie, app by app, and book by book.
