The boy band have been a runaway success since appearing on ITVs The X Factor. Together since 2010, the band consists of Louis Tomlinson, Liam Payne, Niall Horan, Zayn Malik and Harry Styles, with dedicted One Direction fans known as Directioners.
Notable One Direction achievements so far includes a debut single, What Makes You Beautiful: No.1 in UK and Ireland, the debut album, Up All Night: No.1 in 15 countries, BRIT Award winners of Best Single 2012, and perhaps most impressively - the first UK group to debut at No. 1 in the US with a debut album.
The video for Little Things, which is a 47.9 MB download, was released late last year and is featured on the second One Direction, Take Me Home.
