"Opinions Won't Keep You Warm at Night" is the first single from Kisschasy's second studio album Hymns for the Nonbeliever. The song was released via digital download and single CD in 2007. Kisschasy songwriter Darren Cordeux said in press release track notes, "It is a song about being happy with who you are and not letting other people's opinions of who you are or what you do affect you. At the end of the day what people think doesn't mean anything at all. People thought the world was flat once."
