Details
iTunes is a free digital media player application for Mac and PC. It plays and organizes all your digital music and video files on your computer. It keeps all your content in sync. And it’s a store on your computer, iPod touch, iPhone, and iPad, as well as the Apple TV that has everything you need to be entertained. Anywhere. Anytime.

iTunes can connect to the iTunes Store to purchase and download music, music videos, television shows, iPod Games, Audiobooks, Podcasts, movies and movie rentals (not available in all countries), and Ringtones (only available on iPhone and iPod Touch 4th Generation). It is also used to download Apps from the App Store for the iPhone, iPod Touch and iPad.

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. And 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.
