Songs stored on iTunes can be organized across a range of detailed information, allowing the user to search under a variety of headings, including artist, album, song, or genre. It also contains functions that allow the user to create various playlists, create CDs, or listen to songs most recently added to the user’s library. Additionally, iTunes plays streaming audio from the Internet, connecting listeners to radio stations around the world.

Compatible with both Mac and PC systems, iTunes is an interface to manage Apple Inc.’s popular iPod (MP3 player) and iPhone. Since its beginnings as a digital music library, iTunes has developed many additional features. For instance, in 2003 Apple launched the iTunes Store, which gave users the ability to purchase and download music from the Internet directly to their iTunes library. By July 2007 Within four years the store had sold more than three 3 billion songs, and three years after that (in early 2010) it sold its 10 billionth song. In addition to music, the iTunes Store also offers music videos, television shows, electronic games, podcasts (broadcasts transmitted by and through iPods), and feature-length films for download.

For many years Apple had resisted pressure from various record publishers to abandon the company’s single price point of $0.99 per song. In April 2009 Apple gave in and began selling some songs, typically new releases by established artists, for a premium price. At the same time, Apple stopped the restrictive practice of including digital rights management (DRM) software in songs downloaded from the iTunes Store. This enabled customers to move purchased songs to any equipment or player that supports Apple’s AAC encoding format.

With the release of iTunes 9.0 in September 2009, Apple debuted the iTunes LP format. The iTunes LP bundled select albums with interactive multimedia content, bonus songs, lyric sheets, and photographs in an attempt to create the experience of a physical album for the digital subscriber.
