That's what was interesting about writing with Katy Perry because, again, it's her voice at the end of the day. She's also quite dominant, and she's extremely analytical. I actually quit within the first hour of our first session. I was like, "Can we both agree this doesn't work? Like our whole songwriting dynamic?" And she was like, "I love it. It's like a puzzle to me. It's like a crossword." And I was like, "But this is boring for me. The analysis is totally boring for me. It feels like the enemy of creativity." It was so cool to be able to have that conversation on why we wrote in such entirely different ways. I'm glad I didn't give up on it because I actually did get a song out of it, and we also really had a laugh because we were able to be authentic.
There was absolutely nothing wrong with what Sia said. As an overly analytical person myself, I can relate to Katy's style far more than I can to Sia's, but that's just me. Everyone is different and has different ways of working on their craft.
