Undiscovered - Praia Remix (From Fifty Shades Of Grey Remixed)

This song finds Welsh delving into a 'take it or leave it' approach. She explained to The Line Of Best Fit: "It's about me going through a certain situation and my personal experience. And I guess the key line in that track is 'I can't be something that I'm not.' It's like 'take me as I am or leave it.'" "It's about looking underneath everything and how to figure that out, and my train of thought was on those lines," Welsh continued. "I'd say that was the key line of the song and everything else was built around that."

Welsh collaborated on the song with American producer Emile Haynie, who's also worked with Kanye and Lana Del Rey. She told Line of Best Fit: "He came to London for a week and did a few tracks over here. Then I just went to New York a couple of months ago and went to his studio. That was really cool. So we worked on a few tracks on the album, and I also worked with Dev Hynes before Christmas last year for like a day, and 'Unravel' came out of that, which released through Luv Luv Luv. And then when I went back to New York to work on my writing, and Dev and Emile were there, so I worked with them. We just got in a room together, and it was great to get everyone I worked from the start of the record in the beginning together."

This was included on the 50 Shades Of Grey soundtrack. Welsh told HMV.com: "The song wasn't written for the film, but the producers liked it and wanted it for the film."
