Alessia Cara already had the song's skeleton when she presented it to Pop and Oak during their first session together. After she sang the hook to the pair, Felder immediately thought of "Glory Box." He recalled to Songwriter Universe
"I was looking at Pop and I'm going, 'Oh my God, this chord progression almost sounds like a Portishead song that I grew up listening to.' Now, I'm a '90s kid, so Portishead was a big deal, especially in Europe. But of course, Pop, not having grown up in Europe, said, 'No bro, this doesn't sound like Portishead, it sounds like Isaac Hayes.' So we get into a 10-minute argument about it. Eventually, he played me what he's thinking we should use, and I'm like, 'I'll be damned…this is Portishead.' I didn't know that Portishead had sampled Isaac Hayes. So we were both referencing the same material without even knowing it.
Then we presented it to Alessia and she loved it. She said, 'Oh my God, this is such a good idea.' And from that point, the song came together in about an hour…it flew together. After that first session, we kept on going... it turned into two weeks of sessions. We had a great chemistry, and we kept putting songs together so effortlessly."
