Download Previously Purchased Songs, Apps, and Books: You can download previously purchased music, books, and apps to your devices or computer -- regardless of which one you used to buy it -- with iTunes in the Cloud beta. In iTunes 10.3, you'll find a new Purchased link in the Quick Links section of the iTunes Store. Click it to access the Purchased page, where you can navigate among your music, app, and book purchases. On the right, you'll see a tab that lets you choose between All, which displays your complete purchase history for that category, and Not In My Library, which lets you find items you've purchased but don't have in your computer's library. Click the iCloud Download button next to each item to download them one by one, or click the iCloud Download All button at the bottom.
