>Thanks, that line made me think of "You don't own me" by the Blow Monkeys. Now all day I'll be hearing it in my head...

The term is earworm, actually comes from German Ohrworm (sp?)... check http://www.webmd.com/content/article/61/67505.htm for a good-enough description.

I once just sung half a line from one known Serbian folk earworm song, in the morning while my roommate and I were waiting for the bus. In the afternoon, when we came back, he was still humming it.
