Ego (Halsey song)

"Ego" is a song by the American singer Halsey from her fifth studio album, The Great Impersonator (2024). It was released through Columbia Records on September 6, 2024, as the album's third single. Halsey wrote the song along with Gregory Aldae Hein and Greg Kurstin, while Kurstin, Wyatt Bernard, Michael Uzowuru, and Austin Corona handled its production. "Ego" is a 1990s-inspired alternative rock, pop rock, and pop-punk track driven by guitar and drums, with an anthemic energy and lyrics about Halsey's personal struggles and insecurities with her public persona. It was influenced by Dolores O'Riordan of the Cranberries, whom Halsey impersonated as part of the album's promotion.

Upon its release, the song was met with a positive reception from music critics, who noted similarities with the works of O'Riordan and the bands Garbage and No Doubt. Commercially, the song appeared on secondary charts in five countries, including on the US Bubbling Under Hot 100. An accompanying self-written and self-directed music video for "Ego" was released to Halsey's Vevo channel; it sees the singer playing two gender roles representing two versions of herself. She performed "Ego" at the 2024 MTV Video Music Awards, joined by a garage rock band that included Måneskin's bassist Victoria De Angelis.
