revealed to MTV News this song was inspired by the tsunami that hit Japan in 2011. She explained: "When we first got into pre-production, the earthquakes and tsunami happened in Japan, and we were all just totally glued to paying attention to it, all these incredibly heartbreaking images, and we just [thought], 'Wow,' " she said. "And I was thinking about it a lot. It was consuming my mind, and we were working on that song at the same time. I was kind of working on lyrics at night; we'd practice all day, and I'd go home at night and be working on lyrics by myself. And I came in the next day and was like, 'Guys, I'm going to make this song about the tsunami... I was singing it to [my bandmates] in the car, and everyone was like, 'I got goose bumps.' I'm feeling this human connection with [the Japan tragedy]; obviously, I haven't experienced it, but it was cool to write about something a little bit outside myself, that isn't what I usually do."
