One thing I absolutely love about the new music chart system in the U.K. – whereby songs that are officially downloaded count as single or album sales – is that lots of random songs re-enter the charts. Technically, any song that’s available for download could make a comeback in the charts. So if enough of us bought Kylie’s 1987 hit, I Should Be So Lucky, it could reach number one again!

(Alternatively, if I record a song of me humming for 30 sseconds, and got it for sale on iTunes, that could officially be a song in the UK Singles Chart. The mind boggles. Really. You haven’t heard me hum.)

Alright, unlikely. But during special events or at specific times of the year, people seem to buy and download loads of past songs. So, for example, during last year’s World Cup, loads of old football songs made a comeback. (Like Three Lions, which was first released in 1996.)

Unsurprisingly, now it’s Christmas, we’ve got loads of seasonal songs appearing in the charts. The BBC News website has drawn up a list of these songs – top is Mariah Carey’s All I Want For Christmas Is You which has hit the dizzy heights of number 8 in the charts! Next we’ve got the absolute classic – and one of the best festive songs ever – Fairytale in New York by The Pogues & Kirsty MacColl at number 12, followed a good bit of 80s cheese, Wham!’s Last Christmas at number 23.

Here’s one of my favourite Xmas songs – Merry Christmas Everybody by Shakin’ Stevens. You can’t beat a man with an apostrophe in his name.
