• This bombastic track finds Dan Reynolds apologizing for some unnamed action. He utilizes a gun metaphor to portray his regrettable behavior:
  
  I'm sorry for everything, no, everything I've done
  From the second that I was born and since I had a loaded gun
  And then I shot, shot, shot a hole through everything I loved
  Oh I shot, shot, shot a hole through every single thing that I loved
  
  Smoke + Mirrors lead single "I Bet My Life" has a similar theme of Reynolds saying sorry for his mistakes. In that instance he apologizes to his parents for the "hell through all the years," that he put them through.
• Target spent $8 million to buy out an entire advertising break during the 2015 Grammys showing Imagine Dragons performing the track. The first ever live commercial in the history of the telecast, it was filmed on Las Vegas' Freemont Street. The ad promoted an exclusive edition of the Smoke + Mirrors album available at Target that includes four bonus tracks.
• Directed by Robert Hales (Alicia Keyes, Jack White, Gnarls Barkley), the video was inspired by surrealist painter Tim Cantor's album artwork. We see the band dress up as the subjects of the San Diego-based artist's 's paintings while the rest of the scenery unfolds behind them. Cantor also features as the live depiction of one of his paintings.
• Reynolds was brought up in a Mormon household, and this song reflects a sense of guilt that the Imagine Dragons frontman has struggled with since his school days. "I've dealt with a guilt complex since I was young," he told The Independent. "Everything that matters in my life, all of those things I feel I've messed up. I never feel satisfied. I was always the black sheep in the family, always getting into trouble. All my brothers were doctors and lawyers and I was getting the worst grades. And I slept with a girl."
