It's no secret that Mariah Carey [1]'s "All I Want For Christmas Is You" is one of the most iconic holiday songs ever. All you have to do is listen through a dozen or so covers [2] before you realize it's all anyone wants to sing from Nov. 1 all the way through the New Year. But, hey, a classic is a classic, and who are we to turn down another great cover? Case in point: Sophia Grace — whom you might remember from her various appearances on The Ellen DeGeneres Show [3] — has dropped an informal a cappella version of the song. Grace has clearly come a long way since her "Superbass" days [4]. I mean, just listen to those pipes.
