A debate has been raging internally over the influence of the music on iTunes commercials on the mass population. If you recall and look past the U2 and Coldplay commercials of the recent past, you’ll recall how one commercial helped launch the career of a band called Jet, propelled Feist into a different atmosphere where she is now headlining Ravinia Festival for over 20,000 people this coming Friday night, and more recently exposed us to The Ting Tings. You can’t honestly tell us that “1,2,3,4” never stuck in your mind, or that the catchy “Shut Up and Let Me Go” currently on the commercial didn’t get your attention. What other songs that you remember took off because of use at the right time in a particular commercial, movie scene, or television show?
