It's officially been ten years since One Direction formed on The X Factor and became the biggest pop boyband of all time.
Whether you're a fan or not, the omnipresence of the teenyboppers has ensured that you'll know at least one of their songs, despite your best intentions.

You have ninety seconds to complete the lyrics of these ten tracks... good luck!
