A music management program created by Apple. Its features include crashing your computer, crashing itself, constant freezing during sync, randomly reformatting your ipod, suck performance to a crawl, links everything you do to the Itunes Store, and just all around being a pain in the ass.
Its like Itunes has a mind of its own. I leave the room for one minute and all my music is gone! At least it brought up the Itunes Store right after it ate all my songs, so its all good!
