Do we have not just a new Christmas song but the happiest Christmas song of all? Dr. Joe Bennett is a musicologist at Boston Conservatory and he thinks he's figured out the formula for it. 

After studying 200 Christmas songs, Dr. Bennett created "Love’s Not Just For Christmas", with a focus on lyrics, tempo, keys, Santa, sleigh bells, and overall holiday cheer. The song uses the word Christmas 21 times, which apparently invokes the maximum happiness in listeners.
