If you've seen the iPod Nano ad featuring "1234" by Feist, you probably have the song stuck in your head. You're not alone: Since the TV spot first aired last month, the song has shot up the iTunes charts, hit No. 4 on SoundScan, and propelled sales of the Canadian singer/songwriter's album "The Reminder," USA Today reports.
That's fine by Leslie Feist, who found her sound after blowing her voice out touring with a teenage punk band, an experience that led to her "escape to melody." She isn't afraid of becoming "the iPod girl," Feist says: "If I was to stop dead still in my tracks and never make another move, that could maybe be the case."
