I agree with Jim and Bill. It is not a fair comparison because of the changes in technology allowing faster product turnover. To my way of thinking, if downloads had been available during the time of the Beatles and/or Elvis... surely there were others, Mariah and Madonna would not even make a blip on the radar in comparison. But then... who am I to say... just an ordinary old guy who was around (as a child) during WWII.

Music is in a constant state of change and re-invention.
