Cardle released the single under the new name 'When We Collide' after being crowned this year's X Factor champion last weekend.
"I leapt at the chance to do it because it's not your average winner's song," Cardle explained to BBC News. "It's not cheesy and I'm sorry if I've ruined it for people, but it's credible.
"I understand why there will be a backlash, but give me a break," Cardle added.
'When We Collide' is expected to top the UK singles chart this weekend to become Christmas number one.
