The Quintessential Pop Song

There's not a much sweeter song that ABBA has made to date than S.O.S.

It's a pitch-perfect off-the-wall song that starts slowly with a melancholy guitar and piano, working into a beautiful vocal work that emotes much more than was evitable in the lyrics, pen-and-paper.

It evolves into a sigh of relief and bloodpumping pop/rock ascending chorus, which explodes into a minor-noted, happy/desperate "When you're gone" wave of foot-stomping purity.

A perfect song (if such existed) that is as underestimated then as it is now. It's songs like these that paved the wave in ABBAs albums for those like Madonna and the Spice Girls included the dance-pop craze that exploded over the next two decades and extended into the 21st century. Excellent job, ABBA.
