Frontman Gary Lightbody told the Irish public broadcaster RTE: "This is the purest love song I've ever written. Even more so than 'Chasing Cars.' It's luxuriating in the beauty and wonder of someone you love with all your heart."
A Hundred Million Suns represented a lyrical shift for Lightbody, who previously had been best known for his break-up songs. However this tune is one of several positive love songs that the Snow Patrol frontman penned for the set. He explained to The Sunday Times October 5, 2008: "The problem I've always had with writing about love is that you don't really stop and think about it when it's occurring. This time, I made myself think about it - how to fit it into words. The new lyrics took a lot longer than usual, but I'm proud of them." Lightbody added that the band's producer, Garret "Jacknife" Lee has helped him with his lyric writing. He explained: "Sometimes I come up with a good line, but it sounds clumsy. Lyrics are as much about how the words sound as they are about the meaning. Garret drilled that into me."
Country star Slim Whitman's version of the 1920s song "Rose Marie" spent 11 consecutive weeks at #1 in the UK in 1955, a record until 1991 when Bryan Adams’ "(Everything I Do) I Do It For You" spent 16 weeks at the top.
