This is one of two tracks on Sucker
that Charli wrote with Rostam Batmanglij from Vampire Weekend. (The other one is "Need Ur Love
.") "He's one of my favorite people - he's become one of my favorite people to work with," she told Digital Spy
. "He's like a brother to me, when we're together in the studio it goes two ways - either it's great or we kind of want to kill each other."
"He's just such an intense person to work with and he really pushes me because we write really differently," Charli added. "He likes to take his time and go through every single thing until it's perfect and I like to not take time at all. I like to rush and just do it, you know?"
