The song "Icarus" by Julia Michaels is about a relationship that seemed perfect on paper but ultimately ended in heartbreak. Michaels compares herself to the mythological figure Icarus, who flew too close to the sun and fell to his death when his wings melted. Michaels feels that her obsession with her partner was more like a curse than a blessing, and despite all their promises, their love eventually turned to rust and left her feeling burned. In the chorus, Michaels sings about the pain of getting too close to her partner's heart and turning to dust as a result. She didn't realize that their love could be so dangerous, and she tries to let go of the poison of their relationship and fly away from it. Overall, "Icarus" is a cautionary tale about the dangers of getting too invested in a relationship without realizing its true nature. Michaels urges listeners to be aware of red flags and not to hold onto a relationship that is ultimately toxic.
