Songfacts®:

• This Dance-Pop track originated with a demo sent by British songwriter Dev Hynes (Solange's "Losing You," Mutya Keisha Siobhan's "Flatline") which was inspired by a failed relationship; Ferreira then modified the original lyrics and structure along with her producer Ariel Rechtshaid.
• The song was released as a single in the UK on April 14, 2013 and included on the 2013 Now That's What I Call Music! 46 compilation album in the US.
• Ferreria and Hynes had been friends but the pair fell out over comments she made as to whose song it was. Ferreira told The Guardian: "He wrote the demo, and I've always given him credit, all I said was that the song wouldn't have been made without me on it. I think it's a shame because Dev's really talented and he's my friend. Well, was my friend – it's kinda sad that we can't be [friends] now."
• Ferreira sung this on her debut television performance, during the January 7, 2013 episode of Late Night with Jimmy Fallon.
• The track was critically acclaimed, with several publications and music blogs listing it among their favorites of 2012. New York magazine named it the best song of the year saying it, "has feathery grace and weary melodies, magic and sparkle, and feels as warm as curling up next to the radiator on a cold day."
