The month of September has many great, earworm-worthy songs dedicated to it. Earth, Wind and Fire's disco-funk hit “September” is perhaps the most famous of the bunch, with honorable mentions for Green Day's “Wake Me Up When September Ends” and the Kurt Weill standard “September Song” (by Frank Sinatra or Lou Reed, choose your poison), among enough other contenders to form a respectable themed playlist. September is a reliable musical metaphor for getting older, breakups and loss, nostalgia for lost innocence and the slow encroachment of darkness.
