Billie Eilish just dropped her first single of 2019, “WHEN I WAS OLDER.” Produced by her brother and frequent collaborator FINNEAS, the heavily Auto-Tuned track is inspired by 'Roma,' the Golden Globe-winning film by Mexican director Alfonso Cuarón. The movie follows a young maid who works for an affluent mother of four in 1970s Mexico City, telling a story of class, motherhood, and hardship.
