The track reached number one on the music charts in 26 countries, including Italy, the Czech Republic, Russia and the United Kingdom.

[4] By the end of 2013, the song was the sixth fastest-selling single of the year in the UK, selling 145,000 copies in the first week.

[7] Although Naughty Boy originally intended to write the song with Emeli Sandé, she was on tour at the time, and he wrote it with Sam Smith instead.

The piece is performed in F♯ minor, with the chord progression of F♯m—C♯m—Bm followed for most of the song, and Sam Smith's vocals range two octaves, from C♯3 to C♯5.

"The track has tones of liquid drum and bass and old-school garage, and a hook layered with a Hindi-Bollywood sample".

[16] The video is directed by Ian Pons Jewell (who studied at the University College for the Creative Arts, now the University for the Creative Arts)[17] and shot in four days[10] in La Paz, Salar de Uyuni and Potosí (Cerro Rico), Bolivia.

Ian Pons Jewell was commissioned by Virgin EMI to create the concept for the video, which focuses on a child's magical journey.

This man could be the representation of the "Ekeko", a South American figure representative of good luck and abundance.

The boy is walking the dog along a city street, in what is inferred to be La Paz, Bolivia, and he goes into a store front and downstairs.

He holds the heart in the air, the boy looks at him and then slips it inside the jacket pocket of the dusty man.

The boy then looks onto the road and sees a traffic policeman dressed in an unusually colored police uniform with an elephant-like mask covering his face.

This figure is reminiscent of artists and clowns who often perform on the streets in South American cities for money.

They walk along disused railway tracks and pass a discarded, unplugged television that still shows images on the screen.

Their journey takes them across long plains of salt flats, with the traffic policeman carrying the sleeping boy and the dusty man walking the dog.

[citation needed] Lewis Corner of Digital Spy gave the song a positive review, stating: As the Wizard of Oz reimagining in the accompanying music video suggests, Naughty Boy is at his best when presenting tales of heartbreak with an otherworldly streak.

"Yes our love is running out of time/ I won't count the hours, rather be a coward/ When our words collide," newcomer Sam Smith confesses to [their] beau over rattling beats and bewitching synths.
