Leland told Billboard
magazine the story of the song:
"The idea for 'Fetish' came from a session that was part of a two-week long writing camp for Selena. Normally, labels or publishers put together writing camps, but this was something we organized ourselves. At the time I had just finished working with Gino Barletta, Chloe Angelides and Jonas Jeberg on Daya's debut album Sit Still, Look Pretty
, so we just shifted our focus to Selena. At the end of the two weeks, we listened to everything we had written and 'Fetish' seemed to be the obvious standout.
From there I took the song to The Futuristics, who I had recently met. I was a fan of the duo's work on Machine Gun Kelly and Camila Cabello's 'Bad Things
' They worked with Jonas on co-producing the song and nailed it.
We sent it to Aaron Bay-Schuck at Interscope Records. He was amazing about keeping me in the loop with everything, and I trusted him completely. Once Selena got the song, she tweaked some things and made it hers. It was a really fun process to watch."
