A childhood belief about songs

When I was little we used to go to a diner after church every Sunday to have breakfast. Each table had a jukebox where you would put a quarter in and hear a few tunes. I was about 4 or 5 at the time, and used to wonder how the band knew to start playing the song I wanted after I put the quarter in. I figured the quarter must have traveled down a long tube into a back room in the restaurant where a monkey would catch the quarter and bring it to the band, and they would say "Thanks!" and start playing. The only thing I couldn't figure out was how the monkey was able to tell them to play "American Pie" by Don McLean and not one of the other hundred songs in the jukebox. Hmmmmmmmmm.....
