A sullen mind describes someone who is sulky and gloomy and this song finds Ryley Walker explicitly addressing his own depression. He told Mojo: "Depression has been such a part of my own reality. I've been addicted to drugs since I was very young, using coke, speed and downers for a very long time. That causes a lot of depression. I've had great periods of sobriety but I always go back to it."
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."
