iTunes is available as a free download for Mac OS X, Windows Vista, and Windows XP from Apple's website. It is also bundled with all Macs, and some HP and Dell computers. Older versions are available for Mac OS 9, OS X 10.0-10.2, and Windows 2000. iTunes is not available for other operating systems.
Users are able to 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, download 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. There is also a large selection of internet radio stations to listen to.
