The song was written by Gary Lightbody in
Los Angeles with producer Jacknife Lee. He wrote it at the request of the band's label in the United States for pop singer Gwen Stefani's then upcoming album. However, Stefani rejected it. Later, Lightbody allowed
Pussycat Dolls lead singer Nicole Scherzinger to record it. Scherzinger had loved the song, and felt grateful and "blessed" upon being given permission to record it, even calling it an "honour" to sing something written by Lightbody. Scherzinger felt influenced by the Northern Irish Lightbody's accent, and attempted to record the song with an accent herself, with Lightbody acting as the producer. Though she was nervous about doing justice to the song, she was relieved when Lightbody told her that her singing had made his mother cry. According to
ASCAP, who register recordings and song rights in the US, The Pussycat Dolls also recorded and registered the song. When Snow Patrol's label in the United Kingdom heard the song, they were shocked to learn that Lightbody had given away the song in the first place. Where Scherzinger's recording was a soft and slow song with an electronic beat, the new recording was far from that. The band changed the texture fully to predominantly electronic and synth. Drummer
Jonny Quinn called the song a progression for the band. The song is about "loving someone so much that you get exasperated they aren't showing the same amount of passion that you are".
The Denver Post described the song as an "electronic-infused, '80s-kissed track". ==Promotion and release==
