'Divergent' Exclusive: Ellie Goulding Reveals Soundtrack Secrets

'I wrote a song called 'Beating Heart,' ' Goulding tells MTV News, and she's not stopping there.

Late last year, when the first clip from "Divergent" premiered, it rather prominently featured Ellie Goulding's "Dead in the Water" ... though, in a subsequent interview, director Neil Burger wouldn't confirm if the song would appear in the final cut of the film, saying only "she's going to do some music."

On Wednesday morning (January 22), during an appearance on "Good Morning America," Goulding went one step further, revealing that she'd contributed plenty to the movie, including a brand-new song that would appear on the film's soundtrack.

Of course, she stopped short of actually naming that new song ... which is where we come in. Because during a recent sit-down interview with MTV News, Goulding was ready to reveal all about her brand-new track, and the work she's done on the film's soundtrack.

"I wrote a song for 'Divergent,' called 'Beating Heart,' and it's being used for the soundtrack," she said.

Goulding added that she recorded instrumental tracks with orchestral accompaniment (she also posted an Instagram pic of the sessions last week), and that the music they made will definitely surprise both her fans and Initiates alike ... both in the way it sounds, and the way it will be featured in the film.

"I was recording with an orchestra for 'Divergent,' and my voice is kind of woven into the instrumental bits of the soundtrack," she explained. "So, like, I basically got to go into the studio, and just be put in front of the microphone for a few hours and sing whatever I wanted to sing. Not even words, noises and sounds, too. I listened to a lot of Hans Zimmer and Lisa Gerrard, that kind of stuff."
