Which Green Day album features the song '21 Guns'?

The Green Day album featuring the song “21 Guns” is 21st Century Breakdown. The song is the record’s sixteenth track and became its second single, pairing a large arena-rock chorus with lyrics about conflict, patriotism, surrender, and the emotional cost of war.

21st Century Breakdown was Green Day’s eighth studio album, released internationally on May 15, 2009. Like American Idiot, it is structured as a concept album or rock opera, though its story follows different characters and is divided into three acts: “Heroes and Cons,” “Charlatans and Saints,” and “Horseshoes and Handgrenades.”

A frequent mix-up comes from the album’s political themes and Green Day’s catalog. American Idiot also contains major protest songs, while Revolution Radio arrived years later with another politically charged sound. “21 Guns,” however, belongs specifically to 21st Century Breakdown. The track was written by Billie Joe Armstrong, with David Bowie also credited as a composer because of a melodic similarity involving the chorus.
