John Mayer's New Song Is All About Being The Side Piece!

John Mayer is back with a new track, and it's full of the riffs and romance we've come to expect -- but the perspective is now shifted from being the boyfriend to being that one ex you still hook up with.
We're not sure if it's specifically about Katy Perry, like I Still Feel Like Your Man, but it definitely has that same heartachey twinge.
