Organisers of the Brit Awards have had to add extra songs to the best single category after admitting they made a mistake with the original list.
Natasha Bedingfield's These Words now joins the list of nominated singles
They said the original list had been drawn up with the wrong timescale, and that the 2004 chart year was made up of 53 weeks instead of 52.
It will now feature five new songs including tracks by The Streets, Keane and Natasha Bedingfield.
They join the list that already counts Band Aid 20 and Will Young.
The five new singles that have been added to the award are: George Michael's Amazing, Keane's Everybody's Changing, Natasha Bedingfield's These Words, The Streets' Dry Your Eyes and Sugababes' In The Middle.
The category is voted for by listeners of commercial radio stations in the UK.
The five songs that had already been in the list were: Band Aid 20's Do They Know It's Christmas?, Jamelia's Thank You, LMC vs U2's Take Me To The Clouds Above, Shapeshifters' Lola's Theme and Will Young's Your Game.
"It has been brought to the organisers' attention that the 2004 chart year comprised 53 weeks rather than 52, running from 28 December 2003 until 1 January 2005," a Brits statement said.
"To avoid any ambiguity and in the interests of accuracy and fair play the Brits committee has decided to expand the nominations list to ten," the statement said.
Money raised from text message voting in this category will go to the Brit Trust charity, which has pledged £500,000 to help victims of the Asian tsunami disaster, through Save the Children.
"The Brits is committed to ensuring the accuracy and integrity of all of our awards, both the publicly-voted and the Brits Academy-voted categories," a spokesman said.
"A happy side-effect of this decision is that the British single nominations now look more exciting than ever."
