CAR-ISTMAS CRACKERS

Experts devise perfect playlist driving home for holidays

- BY CHARLIE BIGGS-THOMAS

A MUSIC expert has developed the world's happiest Christmas car playlist 'guaranteed' to keep everyone happy according to science.

Dr Claire Renfrew, a music psychologist, sifted through hours of tracks to find the perfect songs, with all the tunes adhering to a scientific formula.

According to the equation, the secret to a dopamine-boosting song is a combination of being in a major key, featuring bright and energetic vocals, playing at 100-140 BPM, with a simple catchy chorus.

And the tune that scientifically hits all the right notes is Brenda Lee’s Rockin’ Around the Christmas Tree.
