A scientist is claiming he has created the "happiest Christmas song ever." The song uses a formula designed to produce the perfect festive tune. It's a three-minute track featuring sleigh bells rining in the chorus and 21 mentions of the word "Christmas" - two things proven to evoke happiness in people.
The song is called 'Love’s Not Just For Christmas' created by Dr Joe Bennett, a Boston Conservatory musicologist.
"There is no simple formula for a successful song, and in practice, songwriters combine their own experience, musical skills and personal creative preferences when writing," he said.
He studied the lyrics, tempo, musical key and vocals of 200 Christmas songs.
The song was recorded by the London Community Gospel Choir and there will be live performances to make shoppers happier at Intu shopping centres around the UK over the Christmas period.
So what do you think? Does this song make you SO happy or not so much?
