It's been around forever (in tech time, more than 10 years is forever) and has revolutionized music listening and music buying. It's so basic, most of us don't give iTunes a second thought. But it's a powerful software application that lets you acquire, manage and listen to music. Approximately 70 percent of the music downloaded in the U.S. is purchased through the iTunes Store [source: Keizer].
If you have iTunes on your computer, you can coordinate with Apple mobile devices like the iPad and iPhone. You can load music wirelessly for on-the-go listening. Or you can purchase tunes from the iStore and have them delivered directly to your iPhone. A new feature is the iCloud, which lets you store all your music on remote servers, then download to any device you want.
Apple also offers Ping, a music social network. This app lets you post songs (or photos, videos and comments) from inside iTunes. Your followers can buy the songs with a click. Ping will alert you to what your friends are listening to, too, and what your favorite bands are up to.
