“I’d never written a song for a movie before,” Kesha told the Songwriter Roundtable on writing her song “Here Comes the Change.” “So I went and saw the movie On the Basis of Sex first,” but called the idea of writing this song “kind of daunting.”
The film, starring Felicity Jones, tells the story of the early life of Supreme Court justice Ruth Bader Ginsburg, something the singer considered a “big task.” “After you watch what she’s done for women, I felt even more overwhelmed and I was like, “Oh, shit, this is a big task,” she said.
When it comes to her songwriting abilities, Kesha says, “Music is something that almost gets channeled through me. You never know if you’re going to lose it, like I’ll wake up one day and I won’t have my magic power.”
Despite fearful over losing her songwriting “magic power,” the singer finds the process “cathartic.” “After I write, it feels so cathartic,” she said. “I love knowing that as a woman I can be self-sufficient. Something nobody can ever take away from me is my ability to write. That makes me feel safe.”
Kesha has two career Grammy nominations for her album Rainbow and her song “Praying.”
