"Gotta wear your crown or your tiara / Now is the time to bust out the mascara / Who needs shade, there's nothing dullah," Meryl raps. "We're living life in full technicolour / But if your sparkle starts to fade / Go out and start your own parade."
"And if somebody starts in with new drama / Just go high like Michelle Obama," she adds in the tune, which was written during post-production because director Ryan Murphy decided the movie needed to "end on a high."
Co-songwriter Adam Anders told USA Today they wrote a female-empowerment pop/Broadway hybrid "that would encompass all of the emotions of the film, but wrap it all in an uptempo banger you can dance to."
"Of course, we had to do this all during Covid, so it all had to happen via Zoom sessions as we were locked down," he assured.

"We wrote a song that was a sad song, but it didn't fit with the tone of the movie," Ryan Murphy said. "And then we got to the end of the movie, with the end-credit design sequence. When I saw that, I think we needed an end-credit song that's about the women. It's about the female power in the film. I told the songwriting team and the composer, 'Let's do something upbeat, that we can send people out in a celebratory fashion, and let's have all the women do the vocal tracks. Furthermore, let's have Meryl Streep rap."
