Who Sings That Christmas Song on That K-Mart Commercial?

Is there that one tv commercial that everytime it comes on, your kid will drop everything and run right over to look at the tv? Today, my almost 2 year old daughter, Willow, was busy primal screaming in mid-tantrum over me not letting her eat a piece of dropped cheese, when this one K-mart commercial came on. You know, the one where it sounds like it's Beyoncé's long lost cousin is singing "Merry, merry, merry, merry Christmas! Hark all the bells..." It's so freaking catchy, that now even I drop everything and run over to watch the commercial. Freaking K-Mart!! You got me hooked on that (song) hook!

So I did some investigating and found out it's Asia Bryant, Carol of the Bells. Mystery solved! (Watch, as soon as I stop typing this to watch this video, Willow will predictably drop everything to run back over to watch this on Youtube with me in 3...2...1!)
