Although Lady Gaga wasn't at Sundance, the singer helped launch The Hunting Ground, a documentary about college campus sexual assaults, by announcing on Twitter that her song "Till It Happens to You" soundtracks the film's end credits. Written with Diane Warren, who left the Park City festival early due to a bout of laryngitis, the track comes just weeks after Gaga herself revealed she had been raped when she was 19. Warren says Gaga "brought some really cool stuff to the [song] -- she sounds amazing on it." Gaga's "Swine" also is featured in the film, which opens March 20.
