As traditional as Christmas jumpers and the frantic search for Sellotape, the annual race for the Christmas No.1 spot is now a full-blown national pastime.

All the usual suspects are on hand, including reality TV show winners, charity singles, novelty records and, of course, a social media backed campaign to get something a bit aggressive to the top spot, because anarchy.

Most bookies have now released their front-runners, naming The X Factor winner as a favourite for the top spot on December 25th. So let's take a look at the runners and riders...

The X Factor winner
There are three acts left – Luke Friend, Nicholas McDonald and Sam Bailey – and Cowell is sure to be looking for a no.1 after the two previous winners, Little Mix and James Arthur, failed to secure the top spot.

Like Rage Against the Machine in 2009, The Aussie rockers are the subject of a grassroots Facebook campaign to get their stomping Highway to Hell to number one. And with 152 thousand likes, it's certainly on the way.

The Big Reunion
Like some kind of terrifying pop chimera, the cast of The Big Reunion – including 911, Blue, 5ive, Atomic Kitten and Liberty X – will release a cover of Wizzard’s, I Wish It Could Be Christmas Everyday.

Susan Boyle and Elvis Presley
Bit of a weird one, this. Simon Cowell's BGT discovery has an undoubtedly impressive voice, but do we need to hear her singing with Elvis on a cover of O Come All Ye Faithful? Let's see what the numbers say.

Lily Allen
Currently holding the top spot (at the time of writing) with her cover of Keane's Somewhere Only We Know, from off that there advert, Allen shouldn't be ignored. And neither should the public's appetite for schmaltz.

Listen to AC/DC’s Highway to Hell below. But we're not biased, yeah?
