The song was written by Kygo and Boys Like Girls frontman Martin Johnson, whose other credits include Jason Derulo's "The Other Side
" and Avril Lavigne's "Here's To Never Growing Up
." The Norwegian producer explained to Billboard
"I played him some music, some old school stuff, like Journey's 'Don't Stop Believin'
,' cause I'm super inspired by those old school tracks, and I told him I wanted to do something like this, like something in that kinda area."
It was Johnson who came up with the lyrics including the titular "kids in love," which Kygo felt was just what he was looking for. "It's just so powerful," he explained. "It's just about being super passionate about someone or something and I'm super passionate about music and I felt like 'Kids in Love' was just a great name for it."
