Justin Bieber Video For “Santa Clause Is Coming To Town”

J.B. goes old school claymation for the video for "Santa Clause Is Coming To Town".  Even incorporating some footage from the classic TV special of the same name.  What is most obvious here is that Justin's voice is no longer that of a 13 year old.  Do you think that he should re-record his old stuff with his new voice?
