The title track quickly kicks into a familiar Green Day three-chord blast, but morphs into multiple movements like some of the more rock-opera-heavy numbers on American Idiot. “My generation is zero/I never made it as a working class hero,” Armstrong sings, making a reference to the John Lennon track the band covered in 2007. After a big drum breakdown, the song winds into a slower “Bohemian Rhapsody” moment. By contrast, “Know Your Enemy” is a straight-ahead rock song with a chanty “oh-way-oh-way” refrain. Opening powerfully like an AC/DC track, Cool drums furiously as Armstrong sings “Silence is the enemy so give me revolution.”
