Ah - another round of masochistic torture, eh? It's absolute madness to only pick one song from each year, but in the absurdly reductionist spirit of proceedings, and going by UK single release dates...

1975: Bruce Springsteen - Born to Run (it actually sounds incredibly ahead of its time, I was just thinking).

1976: ABBA - Dancing Queen

1977: David Bowie - Heroes

1978: Bee Gees - Night Fever

1979: Gary Numan - Cars or Buggles - Video Killed the Radio Star. I cannot choose between them. Do not make me chose!
