Two bonus tracks were also included with exclusive editions of the album on iTunes and Amazon MP3 respectively: "Coming Around" and "Silent War". The album's title is taken from the end of the LP's first song, "What I Wouldn't Do", where Sudol sings: "It was now and we were both in the same place / Didn't know how to say the words / With my heart ticking like a bomb in a birdcage / I left before someone got hurt." In an iTunes podcast about "The World Without," Sudol revealed that she felt Bomb in a Birdcage is about "two totally messed up people trying to stay afloat despite all the odds."
