Jonsin originally recorded the track with British songwriter Steve McEwan. "Me and Steve McEwan actually wrote the song, we actually did it here in New York on guitar — it was just a guitar vocal on an iPhone," the producer told MTV News. "We took the idea later in Miami, like three months after, and produced the track."
Jonsin's manager suggested that he send the track to Eminem. "He had me strip down the verses, take them out, and make the track a little more hip-hop, and he sent it out," he said. The song's chorus acted as a guide for the Slim Shady to do his own thing. "The chorus was based off of a chase, a guy who's chasing after a woman that he's crazy about," Jonsin said of the theme. "He loves her; she's everything to him. I'm a rocket ship aiming at her heart, her heart's the moon — I'm going full-on."
"I didn't really believe that it would end up on Eminem's album, let alone be a single," he added.
