Happier - Breathe Carolina Remix

This song was written by Bastille's vocalist Dan Smith with Steve Mac (Clean Bandit's "Symphony," Ed Sheeran's "Shape Of You") in 2017. It finds Smith in a relationship that has run its course, and he recognizes the uncomfortable truth that love sometimes involves stepping away. He tells his romantic interest that he wants her to be happier, so he's going to leave her even though the image of his lover being with someone else is "eating me up inside."

Bastille saw potential in the song as a collaboration and hooked up with Marshmello to add some of his EDM beats. They were surprised with how the American producer was able to produce an upbeat song from such downbeat lyrics. "We had a really interesting time getting to work on it with Marshmello who managed to find some euphoria in a pretty melancholy, direct song," Smith told NME. "It's always good to step into somebody else's world for a minute and we're excited to be a part of it."

Other UK acts that Marshmello has collaborated with include Anne-Marie ("Friends") and James Arthur ("You Can Cry").
