In the song, Goulding sang about, "And I'm not sleeping now, the dark is too hard to beat," which she attributed to only being able to sleep bathed in lights. "I named it that because I never used to sleep with the lights off," Goulding said. "I still don't, in fact. They make me feel safe and I wanted the album to be something that I could look back on. Your first album is the most important thing, you know, and I just thought it fit my music because it's hopeful and uplifting."
