There’s a news story right now about the ‘Happiest Christmas song’, a commerical research project I was asked to undertake recently to provide statistics about the characteristics of the UK’s favourite Christmas songs (Spotify streams, Christmas 2016). It resulted in the following song, penned by the remarkable Harriet Green and Steve Anderson, two super-talented and mega-credited UK songwriters. The song is below – I think it came out great, but judge for yourself.

Academics who are interested – here’s the analysis paper – a simple list of musical and lyric traits by popularity, with some speculative commentary about cultural trends (complete with extra-Christmassy red and green data charts). There’s also a ‘making of’ video at the bottom of this post.
