When Niall Horan, Liam Payne, Harry Styles, Louis Tomlinson and Zayn Malik were put together by pop supremo Simon Cowell, no one would have expected what a huge global sensation they would become. After finishing third on the British X Factor in 2010 Simon Cowell signed One Direction to his record label Syco records. Using the tremendous power and reach of social media the boys became a favourite with millions across the globe.
A year after being signed the English/Irish Boyband released their first studio album entitled Up All Night. The album was hugely successful, it featured the smash hit single What Makes You Beautiful, and went multiplatinum in every corner of the globe.
Success continues, and even despite the departure of Zayn Malik in March 2015 and the group's current hiatus, One Direction remain one of the biggest bands in pop history.
With songs such as Best Song Ever, Story of My Life and Perfect, to pick your favourite One Direction song is extremely difficult, but can you decide which 1D track is the best?
