• Megan Trainor wrote this empowering feminist anthem with THE ELEV3N. She also co-penned "Kindly Calm Me Down" with the New York City production team.
  
  Trainor said in a track-by-track: "'Woman Up' is a song that I've heard for a long time. It was originally written for another artist in the UK and when I heard it I said 'can I please sing that demo for you,' when I was 18-years-old and then years later I said 'Whatever happened to that song' and they said it went out and I was like, 'can I rewrite the verses for my album?' and they said 'Why not, why don't you do that' and we rewrote it, Taylor Parks rewrote it with me."
  
  Actress and songwriter Taylor Parks had a recurring role in the Nickelodeon sitcom True Jackson. Her other songwriting credits include include Fifth Harmony's "Bo$$," Mariah Carey's "Infinity" and Alicia Keys' "In Common."
• Trainor explained the song's meaning: "This is a very empowering 'woman up' song about when you get down. Don't just be sad at home. Put some heels on, let's go out. Woman up!"
