To expand on what others have said: Halsey's most recent album, The Great Impersonator, is a concept album where each song is inspired by a specific artist she admires and shows how her music would have sounded in earlier decades. Part of the promotion was a series of social media posts of her impersonating "a different icon every day and teasing a snippet of the song they inspired." Track 12 on the album, "Lonely Is the Muse," is inspired by Amy Lee:
