"Green Light" is a song recorded by New Zealand singer Lorde, serving as the lead single for her sophomore studio album Melodrama (2017). It was written by Lorde and Jack Antonoff, who also produced the song. “Green Light” is about Lorde’s first major heartbreak and is “the first chapter of the last two wild, fluorescent years” of Lorde’s life before the song dropped. Over those years, 2015 to 2017, Lorde became an adult and moved away from her “glossy idiot god” teenage self and “crossed over” to adulthood. Read more on Last.fm.
