Tell that to the artists Michael...... If I were featuring a special, playing the top 50 HITS of 1977, that's how the show would be labeled today...the top 50 HITS of 1977. "Hotel California" is a number one song from 1977 and still is today a number one song from 1977, as are the other 27 titles that made #1 that year.
You are not seeing it the way I am trying to present this to you. And from your perspective, it all about research. My view is what the listeners would love to hear and what they have been missing for so long. We disagree.
Actually, it was an artist (explaining the tail-off of sales of a formerly huge record) who first explained to me that a hit from 36 years ago is only a hit from an historical perspective, and most people don't view it that way.
