"Til It Happens to You" is a song produced and performed by American singer Lady Gaga. She co-wrote the song with Diane Warren for the 2015 documentary film The Hunting Ground, which deals with campus rape in the United States. The song had leaked onto the Internet through an unofficial recording made at the film's premiere at the 2015 Sundance Film Festival. It was later released by Interscope Records to digital retailers on September 18, 2015. The director and producer of the film had looked for someone influential to write a song for it, and music supervisor Bonnie Greenberg contacted Warren who was interested. She wrote the song with Gaga and producer Nile Rodgers accompanied them during the recording, providing his suggestions.
