iTunes is a digital media player, written by Apple Computer, for playing and organizing digital music and video files. Additionally, the program connects to the iTunes Music Store which allows users to purchase digital music files that can be played by iTunes.

The player has gained and maintained a reputation as being easy to use while still providing many features for obtaining, organizing, and playing music. iTunes is also the principal way to manage the music on Apple's popular iPod digital audio player. The program is freely downloadable and is also supplied with Mac OS X as well as Apple's iLife home-application suite.
