My laptop has done this more than once. It plays one song from the soundtrack of the movie "Enchanted" over and over again. I don't even own the song, that's what annoys me. I don't know how my computer got it, or where it got it from. It can't be a virus, can it? It's not in iTunes, or a file on my computer. I hit the play/pause button, and nothing happens. It plays over the top of everything I listen to as well. It just doesn't stop. I quit every single application, I restart my computer, and I have even relaunched finder. This is simply annoying. I hate this song so much now, and I just want it to stop playing. Any suggestions?
