Is it something by Bing Crosby, barking dogs, chipmunks or the Mormon Tabernacle Choir?  What does it take to be the “perfect” holiday song?

A scientist claims he's cracked the code of what makes the "happiest Christmas song ever," and he even created a song to back up his claims. His tune is entitled, "Love's Not Just For Christmas," is three minutes long, has bells ringing in the chorus, and mentions the word "Christmas" 21 times.

The formula for the song was created by Dr. Joe Bennett, a Boston Conservatory musicologist.  Bennett says he studied the lyrics, tempo, musical key and vocals of 200 Christmas songs in order to perfect the perfect formula!
