21st Century Breakdown is a song by Green Day Frontman Billie Joe Armstrong told Q magazine May 2009: "That goes from a song about where I come from to what it's like to be in this era, financially. It represents an underdog spirit." The lyric "My generation is zero/I never made it as a working class hero" references the John Lennon song "Working Class Hero," which Green Day covered for the Instant Karma: The Amnesty International Campaign to Save Darfur compilation album in 2007. The 21st Century Breakdown album debuted at #1 in 24 countries.
