While most songs are the regular punk rock the band popularized, others such as the Latino-influenced “Pretty Fly (for a White Guy)” and the psychedelic “Pay the Man” add variety, “so that there’s enough in there so people don’t get bored”. “Pay the Man” was even left off Ixnay on the Hombre for sounding too different from anything else the band had currently made at that time. The structure of the song more resembles progressive rock (having no repetitive sections and no continuous musical theme).
