Composed by James Newton Howard, the haunting folk song's lyrics are by Hunger Games author Suzanne Collins, while "Ho Hey" singers The Lumineers collaborated on the track. In the film, Jennifer's character Katniss Everdeen performs the song -- which she learned from her father -- and it quickly becomes an anthem for the rebellion.

Though the song is now an obvious success, Lawrence confessed to David Letterman in November that the experience of singing on set was "awful."

"I cried on set that day and apparently I'm crying all the time," she said. "I'm like scarred from my childhood because I have a Southern mother who would just tell me that I was amazing at everything, that I could do everything. But, I can't."

"I do not like singing in front of other people," she added. "It's like my biggest fear."
