iTunes is a media player, media library, and mobile device management application developed by Apple Inc. It is used to play, download, and organize digital audio and video on personal computers running the OS X and Microsoft Windows operating systems. The iTunes Store is also available on the iPod Touch, iPhone, and iPad.
Through the iTunes Store, users can purchase and download music, music videos, television shows, audiobooks, podcasts, movies, and movie rentals in some countries, and ringtones, available on the iPhone and iPod Touch (fourth generation onward). Application software for the iPhone, iPad and iPod Touch can be downloaded from the App Store.
iTunes 11 is the most recent version of iTunes, available for OS X v10.6.8 or later, as well as Windows XP or later. It was released on November 29, 2012, one month later than expected, because of a delay by Apple, which explained that it needed extra time to complete the revisions necessary to complete the update. 
Music Managment : iTunes acts as a front end for Apple's QuickTime media player. Officially, it is required in order to manage the audio data of an iPod, iPhone, or iPad, although alternative software does exist. Users can organize their music into playlists within one or more libraries, edit file information, record Compact Discs, copy files to a digital audio player, purchase music and videos through its built-in music store (iTunes Store), download free podcasts, back up songs onto a CD or DVD, run a visualizer to display graphical effects in time to the music, and encode music into a number of different audio formats.
