"Like the Dow Jones Industrial Average — which signifies the health of the U.S. economy for millions of people who understand little about what the Dow means or how it works — the Hot 100 has been around long enough to become both a fixture and a shorthand for the current state of U.S. popular music."
I agree with him that "airplay-heavy charts are deadly. That’s the situation we had in the early 2000s, when iTunes hadn’t been invented yet and the labels had killed off the retail single."
Sadly, he needs to look deeper than his hypothesis of so-called "tyranny" that radio is "The Chief Executive" which undermines a good chart.
Too often it's promotional tactics manipulating radio in pursuit of album sales due to their higher profitability to the label which drives the chart and thus lacks "... checks and balances: the Congress that is the consumer.. (You also need a supply of good songs, obviously, but there’s not much a chart can do about that.)"
Stations (and labels) which ignore their own listener-driven research should not be surprised when the audience complains about too much repetition (aka too many songs I don't like) and looks to downloads for songs they simply like better than the chart hits being spun ad nauseam by radio in pursuit of #1 on the traditional trade magazine rankings.
Old habits are hard to break, but it's time we all rethink what we're doing and why.
