Happier Than Ever was Billie Eilish's second studio album, released in 2021 and written and produced together with her brother Finneas. The album sounded more restrained than her debut, moving between jazz, bossa nova and electropop. Singles including my future, Therefore I Am, Your Power, Lost Cause and NDA preceded the release, and the title track built from a quiet ballad into a rock outburst. Thematically, the album addressed fame, abuse of power and the pressure of media attention. Happier Than Ever reached number one in both the United States and the United Kingdom and earned multiple Grammy nominations.
