iTunes is an audio player for playing and organizing digital music files, and purchasing digital music files in the FairPlay digital rights management format. The iTunes Music Store is the component of iTunes through which users can purchase digital music files from within iTunes.

Users are able to organize their music into playlists, edit file information, record compact discs, copy files to a digital audio player, purchase music on the Internet through its built-in music store, run a visualizer to display graphical effects in time to the music as well as encode music into a number of different audio formats.
