Ghosttown

Madonna wrote this power ballad with Sean Douglas and Jason Evigan, who worked together on Demi Lovato's "Heart Attack" and Jason DeRulo's "Talk Dirty." The other co-writer was Evan Bogart, whose credits include Beyonce's "Halo" and Rihanna's "S.O.S. (Rescue Me)."

Madonna told Billboard magazine the story of the song. "We all get into a room together. They start playing their chords and then we just start thinking about… When I write with people, we always try to come up with a theme. What do we want to write about? So this one is about the city after Armageddon. The burnt out city, the crumbling buildings, the smoke that's still lingering after the fire. You know what I mean? There's only a few people left. How do we pick up the pieces and go on from here? Kind of dramatic. (Laughs.) But not entirely impossible at this stage of the game."

The song is about seeing hope amidst the destruction: "At the end of the day, if we run out of oil and we don't have electricity and we don't have all the modern conveniences, and we have no phones and computers, all we're going to have is each other, is humans," Madonna explained to Rolling Stone. "And that song's about recognizing that."
