Charlie Puth wrote this with Swedish hitmaker Max Martin, who started off by creating catchy pop tunes for the likes of Backstreet Boys, 'N Sync and Britney Spears. Puth told AT40
: "'Then There's You' is a record I worked on with Max Martin, who is like the Pop God of the world. I needed to have one pop-y record on this album. I grew up listening to Backstreet Boys and 'N Sync, and I couldn't have a debut album without having something done by Max Martin. I was so happy he jumped on this."
