That song you sing over and over

Last night I watched a movie called "That Thing You Do!". It was about a band that became famous almost over night. Surprisingly they did that with a manager in "a snazzy RV". After preforming a few times at a pizza place on the outskirts of some Podunk town, their "manager" got an interview with another manager from a big time music recording studio. They went on tour and about the fifth time they sung the song it got be so annoying. I started thinking wouldn't it get a bit tedious singing the same song over and over again? I mean if you were on tour and mixing it up a bit it would be fine, but the same song over and over again? It was a good movie. At the end, of course they played the song AGAIN!
