Out the Wings of a Butterfly" was described by Valo as a "link between 'She Sells Sanctuary' by The Cult and 'Billie Jean' by Michael Jackson". The lyrics were inspired by a legend of immortal souls possessing the wings of a butterfly, and talks about: "Whether you are willing enough to destroy something beautiful to gain yourself some power." According to Valo, the song was chosen as the first single from Dark Light, because it was "the perfect song to describe what's going to happen on the entire album", containing all the signature elements of the band's sound as well. "Killing Loneliness" was partly inspired by professional skateboarder Brandon Novak and his heroin addiction, and talks about the various ways people "kill their loneliness, and with what", while "Behind the Crimson Door" features Valo humming a poem by Finnish author Timo K. Mukka. Valo described "The Face of God" as "Achtung-era U2, with Queens of the Stone Age meeting the Satanic Bee Gees", and "In the Nightside of Eden" as the "prog rock" song of the album, which also makes mention of the Divine Comedy by Dante Alighieri. The band's cover of "Poison Heart" by the Ramones features claps by Sire Records' co-founder Seymour Stein and A&R executive Michael Goldstone. Release and promotion "Rip Out the Wings of a Butterfly" (under the title "Wings of a Butterfly") was released as the first single from Dark Light in September 2005, charting in ten countries, including at number one in Finland, number ten in Germany and the UK, and at number 19 on the US Alternative Chart.

The album would eventually be certified platinum in Finland, and gold in Germany, the UK, and the US, making HIM the first Finnish artist to receive a gold record in the United States. The North American leg of the album's supporting tour began in Portland, Oregon, on 5 October 2005, and continued until the end of November, with Skindred and Flinch serving as supporting acts.
