what's on the box?

Ever have a song pop into your head soemtimes and it won't go away?
For days I have been singing this to myself (or trying to, on account of my testicles dropped already). And I can remember years ago, for some reason, this little gem would float into my head. These are not songs I really "like" (they would never make it onto any CD I compile for repeat play) and yet they are on circulation in my head, popping into my consciousness at random moments. How does this work? Still, at least it ain't this
