The success of this single is not due to the marketing or "mystery" this article suggests. The success of this single is due to the contributions of legendary recording artist AND producer Nile Rodgers, who has written dozens of break out singles including:
Good Times - Chic
We are Family - Sister Sledge
Let's Dance - David Bowie
Material Girl - Madonna
If you listen to this album, it does not have hit songs except for Get lucky. Almost all marketing focused on this single, because it was the only good track.
