Christmas number ones over the years have been everything from cheesy to classic, iconic to reality TV takeover.

With XFactor dominating the spot for seven of the last twelve years, petitions and campaigns have led to the most bizarre of Christmas winners.

There are many that have been so bad, we have completely forgotten about them - Mr Blobby anyone?!

Here's a rundown of the last eight years of number ones. Want to know what was number one in the year you were born? Just use the picture gallery above and scroll across to your year.

Mine was Mary's Boy Child by Boney M, not my favourite. My colleague sitting to the right of me headbanged to Bohemian Rhapsody by Queen, much better, but still not a classic Christmas song. 

Echo:

Rockabye by Clean Bandit featuring Sean Paul and Anne-Marie

A little different to charity songs and reality show winners, this more upbeat hit spent a total of nine weeks at number 1.

Echo:

A Bridge Over You by The Lewisham and Greenwich NHS Choir

A social media campaign helped A Bridge Over You, a charity single recorded by an amateur choir made up of NHS staff, to become Christmas number one in 2015. The song battled it out with Justin Bieber for the top spot and finally (and deservedly) came out on top. 

Echo:

Something I Need by Ben Haenow

Ben Haenow won the eleventh series of the XFactor and was the last winner to have a Christmas number one. Ben managed to hold off Uptown Funk by Bruno Mars, some feat considering the song has been viewed 115 million times on Vevo.

Echo:

Skyscraper by Sam Bailey

Another XFaxtor winner made it to the top spot in 2013, this time it was Sam Bailey with a cover of Demi Lovato's Skyscraper.

Echo:

He ain't heavy, he's my brother by the Justice Collective

The cover of 'He ain't heavy, he's my brother' was performed by The Justice Collective, a group of musicians and celebrities, put together in 2012. The group's aim was to put together a fund-raising record raising money for the various charities associated with the Hillsborough disaster.

Echo:

Wherever You Are by Military Wives with Gareth Malone

Performed by the Military Wives Choir, sung by ladies from Chivenor and Plymouth. It was released on 19 December 2011 following a campaign to make it the 2011 UK Christmas number one. The song was also nominated for Best British Single in the 2012 BRIT Awards.

Echo:

When We Collide by Matt Cardle

Originally titled 'Many of Horror' a cover of the Biffy Clyro hit, Matt Cardle made Christmas Number one in 2010.

Echo:

Killing In The Name by Rage Against The Machine

English DJ Jon Morter and his wife Tracy launched a group on the social networking site Facebook encouraging people to buy the song in the week before Christmas to prevent another winner of the X Factor achieving the Christmas number one. On December 15, the BBC reported the group had more than 750,000 members.
