Researcher Dr Joe Bennett at the Boston Conservatory says that most Christmas songs have a major key (often C major or A major) a tempo of 115 beats per minute and 4/4 time.
Listening to everything from Mariah Carey to Michael Bublé, Bennett created eight thematic categories that the songs fell into: home, being in love, losing love, partying, Santa, snow, religious themes, and peace on earth. The song will also be played at intu's retail and leisure destinations around the country in the lead up to Christmas to inspire the nation to "Get Christmassing".
The end result is a song called Love's Not Just For Christmas, which has been recorded by the London Community Gospel Choir.
"But we can infer listeners' favoured song characteristics by analysing the most popular recordings - in this case, Christmas songs".
He created his three-minute "masterpiece", with help from lyricists Harriet Green and Steve Anderson who have written songs for Britney Spears and Kylie.
Love them or hate them, Christmas wouldn't be Christmas without the usual barrage of festive tunes.
Speaking to the Stoke Sentinel, he said, "Over the years I have been lucky enough to have written and produced Christmas tracks and albums for a number of artists including Kylie, Susan Boyle, and Harriet, who co-wrote this song with me".
As part of the research to create the world's happiest Christmas Song, Mariah Carey's All I Want For Christmas Is You was revealed to be the most popular Christmas song in the United Kingdom, ahead of Last Christmas (Wham!), Fairytale of New York (The Pogues) and Merry Christmas Everyone (Shakin' Stevens).
