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.

Where listening, watching, and playing start:

iTunes lets you enjoy all your music, movies, video, and TV shows on your Mac or PC. When you want to watch or listen to something, you no longer have to look through your CDs or flip through channels — just go to your computer and open iTunes. With your entire media collection in your iTunes library, you can browse everything faster, organize it all more easily, and play anything whenever the mood strikes.
