"The way that you flip your hair gets me overwhelmed," One Direction confess on their debut single. Given their age and their not-so-squeaky clean reputation with the ladies, we're not surprised that something as trivial as lock-tossing could get this lot going - though judging by the rest of the song, it turns they're in fact surprisingly picky when it comes to finding a long-term mate.
Their favourite sort? That endangered breed who are visually stunning but aren't aware of it. "Don't need make-up to cover up/ Being the way that you are is enough," they insist over a toe-tappable melody dangerously similar to Grease classic 'Summer Nights', before launching into a breezy guitar-pop chorus that would probably occupy the intersecting space of a Venn diagram between McFly's 'All About You' and Pink's 'Raise Your Glass'. Like a Forever Friends bear from your high school crush, it's adorable, completely innocent and bound to cause a stir amongst your mates.
