iTunes is a free application for Mac and PC. It plays all your digital music and video. It syncs content to your iPod, iPhone, and Apple TV. And it's an entertainment superstore that stays open 24/7. iTunes can connect to the iTunes Store via the Internet to purchase and download music, music videos, television shows, iPod games, audiobooks, eBooks, podcasts, feature length films and movie rentals (not available in all countries), and ringtones (only used for iPhone).
