I heard it often especially when my parents turn on their iPods and plugged in to speakers. The reason why I'm asking this it's because the song in their iPod only show up as like 'untitled.mp3' or some stuff like that. It's a disco song I think and there's a woman singing and saying doo doo doo doo doo dodoo doo.
Here's a sample I made on Mario Paint Composer: http://www.datafilehost.com/d/431e89ef
