We should have a poll....but as for me, it's a toss up between "Santa Baby" and "Favorite Things."
On second thought, it's "Santa Baby." While I hate "Favorite Things" as a Christmas song, it's OK in context as one of the numbers in "The Sound of Music."
Radio programmers be like, 'Huh? What mean 'Fa-vo-rite Things' no is Criss-muss song? We play forever!'
