Bohemian Rhapsody (1975).

Do They Know It's Christmas (1984). There have been some great Christmas number ones over the years, not to mention a few nauseating horrors and some prize Christmas turkeys, the biggest of which has to be 1993's Mr Blobby, by, er, Mr Blobby.

Normally it would be difficult to cheer yet another X Factor winner taking the spot since they elbowed out the competition in five of six years between 2005 and 2010, while the 2011 winner was yet another reality TV show, The Choir. It is the time of year when music sales are at their highest and self-made acts struggle to get a look-in ranged against singers who have had three months of prime-time TV coverage.

Still, this year's X Factor winner Sam Bailey will be a popular victor because of her generous decision to divide all proceeds between two charities, Great Ormond Street Hospital Children's Charity and Together For Short Lives, which helps children with life-threatening conditions.

As a way of capturing the Christmas spirit, such generosity on the part of singers, be they newcomers or old hands, beats any number of snowy music videos.
