From the beginning of the early 1990's onwards cover versions of old songs were flooding the billboard charts. The economic concept that is behind the idea of covering songs is as simple as effective: The financial costs of such a production are mainly low for the music industry, the creative effort is in most cases also negligible. The desired outcome, namely financial success, is programmed, since one can be sure that a song which the masses already liked once will be liked and bought a second time, as long as the latest style is reflected in the piece.
