Frontman Nathan Leone (from Kerrang! April 4, 2009): "This song is about confessing all the awful things that you have done in your life to someone you love and crying out for help. Hypothetically, say you are addicted to drugs, the only way to get better is to go through withdrawal to get well again. Whether that's in a relationship and you have to break up, or you are in a job and you have to change, it may be terrifying, but you have to go through the hard part to get better."
The Prince-penned "Manic Monday" was the first song The Bangles heard coming from a car radio, but "Eternal Flame" is closest to Susanna's heart, perhaps because she sang it in "various states of undress."
