Mike Posner is readying the follow-up to 2010's '31 Minutes to Takeoff,' and he's released the project's lead single. On 'Top of the World,' he isn't deviating from the pop formula he established on his debut, but he's invited frequent collaborator Big Sean.

Sean wastes no time making himself at home over the twinkling synths as he slides right in after Posner's short hook. "I've been balling out for a minute, still playing like I'm recruited," a punchline-happy Big Sean raps.

The track features production by Diplo and a funny exchange at the end, in which Posner purposely jacks Big Sean's punchline. Posner's untitled sophomore album is on its way.
