"A-Punk" is recognized for its spunky drive and pogo-inducing rhythm, creating an uptempo feel that some found almost too quick for the band's clever melodies to fully breathe. Yet, the lyrical inventiveness, with lines like "His honor drove southward seeking exotica/cut his teeth on turquoise harmonicas," provides a unique and buzzing zip to the song. The flute-aping synths and bottled-sunshine guitars are noted as essential elements of its sound. Playing this song, you're channeling a bright, energetic, and quirky spirit.
