After seeing the latest iPod nano commercial for the umpteenth time, I decided to look it up who performs its catchy little number. It turns out the ipod nano song is 1-2-3-4 by Feist.
After listening to a few of her songs I was hooked, and ended up buying both her albums. Her studio work is great, but she really rocks out live, as evidenced by the following video with her version of the Ron Sexsmith song "Secret Heart."
