You have to admit that that song has to be the one song that will NOT stop playing in your head. That song is going to continue to play in your head for the rest of your life.
Now, imagine, for a second, that you have just gotten in to your friend's car, and that song is playing. But neither of you know what song it is. You both know you've heard it a zillion times before. And lets say your car's RDS thingie isn't telling you what song's playing. And now, a few hours later, you have to know. You just have to know, and you have to know now. Your sister, who is a walking songs + lyrics database is n/a. Googling/Live Searching/Yahooing "dadadadadadada" doesn't help. In fact, you just feel ridiculous typing "dadadadadada" into the search box, but you do it anyway. Because you are desperate. But you get nothing. Searching for the few words from the song that you do remember, like, "shaking your umbrella", and "pour the milk" doesn't help either.
