One Direction's writers have revealed that they intend the boyband's music to be 'vanilla' so as to appeal to as many people as possible.
Carl Falk, Rami Yacoub and Savan Kotecha said that they were aiming to appeal to teens and tweens when writing One Direction's music.
Speaking to Billboard about the lads' cross-Atlantic success, Kotecha said: "It felt like everyone tried to do boybands by going to the cool, hip producers who were coming up.
"We wanted to make it very vanilla. You're aiming for teens and tweens with boyband guilty pleasure music. We weren't trying to be urban or rhythmic, and they happened to share the same vision."
"Each of the songs have signature riffs - something so people can play YouTube versions of our songs," Falk added.
"We wanted to do something where we didn't copy anything right off. We're trying to do our own thing a little bit, even if it's just the guitar parts."
The writer's approach seems to have worked for the boys, at any rate, with two US No.1s and a No.1 and a No.2 singles in the UK this year.
The boys have also enjoyed a successful US tour that included headlining Madison Square Gardens.
In fact, 2012's been so good to the One Direction lads that Mick Jagger even recently commented that they were the new Rolling Stones.

Falk, Yacoub and Kotecha have all previously worked with huge recording artists, working together on songs for Westlife.
Falk has also worked on tracks for Nicole Scherzinger and Taio Cruz, while Yacoub has worked with Britney Spears, Nicki Minaj and the Backstreet Boys, to name a few.
The One Direction boys have been asked to record the charity song for Comic Relief, and will be recording their version of Blondie's 'One Way Or Another' for next year's charity drive.
