In “Lonely is the Muse,” Halsey delivers a haunting ballad that explores the sacrifices made in the name of creativity. The song’s lyrics reveal the inner turmoil of an artist who gives everything to inspire others, only to be left with a sense of emptiness and loneliness. Halsey likens herself to a martyr, someone who suffers for the sake of others, and this theme runs deep throughout the song. The poignant lines about being “reduced to just a body in someone else’s bed” highlight the dehumanizing aspects of being a muse. “Lonely is the Muse” is a powerful commentary on the cost of artistic brilliance, where the pursuit of inspiration often leads to a lonely, forgotten existence.
