# Know Your Enemy (Green Day song)

"Know Your Enemy" is a protest song by American rock band Green Day. It is the third track on their eighth album, 21st Century Breakdown, and it was released as the lead single through Reprise Records on April 16, 2009, and the group's first single since "Jesus of Suburbia", released 4 years earlier. Billboard described the song as being lyrically "just as politically charged as last time (on American Idiot)", having a "Modern Rock radio-ready chorus", whilst the song's producer Butch Vig "brings enough punk sheen for mass appeal." It was the first, and one of only three songs, to top the Rock Songs, Alternative Songs and Mainstream Rock Tracks Billboard charts at the same time. "Know Your Enemy" has been certified Gold by the RIAA and has sold 798,000 copies as of August 2010.

## Release and reception

It was referred to by Spin as sounding "like an out-take from the Dookie sessions". About.com's Bill Lamb said the song was "standard issue Green Day", "not a stroke of genius" and "not on par with their last album", but said it was a "great appetizer" for one of the most eagerly awaited albums of 2009. Pitchfork Media described the track as having "pedantic stiffness" and "nothing more than a rote protest song preaching to the converted". Rolling Stone called the song one of the highlights of the album, praising the punk-oriented sound and calling it one of the "Clash-size bootboy chants" [from the album]. Billboard said that "The lead single from the band's new release, 21st Century Breakdown, finds the group just as politically charged as last time", but also said that "While the subject matter is broad and may be missed by some, "Enemy" has enough charm to amp up the airwaves until (21st Century) Breakdown is released."
Billie Joe Armstrong told Q, "It’s a rallying song. It’s about liberating yourself from a lot of bullshit that you see on TV." The song managed to top both the Billboard Mainstream and Alternative Songs charts at the same time, while cracking the Top 30 on the Billboard Hot 100, reaching number 28. The song entered the Alternative Songs chart at number eight and rose to number one in its second week. It kept the top spot for six weeks.
During their 21st Century Breakdown tour show in Minneapolis on July 11, 2009, Billie Joe Armstrong told the crowd that the song had been recorded on the first day of the Republican National Convention in Saint Paul, MN.
