One

Writing and inspiration
"One" was written by Sky Ferreira and Marit Bergman in less than thirty minutes, and was produced by Bloodshy & Avant, responsible for some of Britney Spears' hits such as "Toxic", "Piece of Me", and "Radar". Ferreira stated the song is about "being numb and wanting to feel love, happiness, sadness—anything, really. It's kind of like the Tin Man wanting a heart." In an interview with Digital Spy, Ferreira elaborated on the meaning behind "One": "It's about that point where you don't feel anything—you don't feel happy, you don't feel sad but you want to feel something. It's a situation I was in and I think everyone's been in. There's always someone in a relationship who wants more attention and starts trying too hard to please the other person. The thing is, the more you try to please that person, the less effort they make because they know you'll do anything they want. It's that stage I'm singing about on 'One'."

Commercial performance
"One" entered the UK Singles Chart at number sixty-four for the week of August 29, 2010.
