Songfacts®:

• Halsey recorded this moody, atmospheric ballad for the Fifty Shades Darker soundtrack. We hear her singing about letting go of her fears regarding giving into her deepest, darkest desires.
  
  I am not ashamed anymore
  I want something so impure
  You better impress now
  Watching my dress now, fall to the floor
  
  The lyrics reflect the erotic tone of Fifty Shades Darker, demonstrating Anastasia's new perspective on her relationship with Christian. Having originally been afraid and sceptical about everything, she's now ready to take what Christian's got to give, and enjoy everything without fear.
• This isn't the first time that Halsey has lent her music to film. Her single "Castle" featured in 2016's The Huntsman: Winter's War.
• Halsey wrote the song with Nasri Atweh the singer from Magic! (of "Rude" fame) and Jason Quenneville the co-producer of "Earned It" (from the original Fifty Shades movie.) It was produced by Adam Messinger, who is Atweh's production partner.
• Halsey discussed the writing of the song during a Beats 1 interview: "It's especially hard to do something that feels unique and feels authentic especially for me because Fifty Shades [Darker] was almost too good of a pairing, too good of a brand mashup especially this film in particular because Fifty Shades Darker is kind of about Anna, the female character, coming into her own on her sexuality and owning it and choosing her freedom and choosing her quality over a life of submission. You know that's very much the M.O. of my project, strong, sexual female mentality so it was almost too easy - I was like how do I do this?"
