The demo/“first version” of “Ain’t My Fault” was played in full on October 18, 2016 via Reprezent Radio, and features different lyrics than the finalised version.

Larsson mentioned the demo in an interview with BBC Radio 1:

I can’t be Becky With The Good Hair, it doesn’t make sense, I would never be proud of stealing a girl’s man and sing about it, it would be very not me. So we have changed the lyrics and now I can proudly sing it without hurting anyone’s feelings. When we wrote it we just wrote it for fun and people loved it, but then I was like whoa whoa whoa I can’t sing this.
