If ‘What Makes You Beautiful’- the debut single from X Factor runners up One Direction – could know its audience any more, it’d have skimmed their bank account and nicked their passport by now.

Aimed solidly at teenage girls (and boys) who are waiting for somebody to be secretly in love with them, ‘What Makes You Beautiful’ is so unthreatening it might have to think twice about holding hands, lest it get overwhelmed.

Not that that’s a bad thing. Channeling their sterling performance of ‘My Life Would Suck Without You’, ‘What Makes You Beautiful’ is exuberant with a catchy ‘oh na na na’ middle eight.

The real genius is that the chord progression is simple enough to be played on an acoustic guitar at a house party. A tenner says this is ‘our song’ to four new pubescent couples by the end of the week.
