Here's an article from RadioWorld about how radio needs to reduce its
clutter.

This is a strong pet peeve of mine. As a one-time radio GM, our stations
held firm on clutter and price, but we were undermined by the competition
and our customers. Of course, my argument was still right... that too many
commercials is an incredible turnoff factor for listeners, and if people
don't listen, no one hears the spots. And our stations remained numbers one
and two, so I know we were doing something right.

Now that I am a listener, I am one of the first to turn away from a station
that plays too many spots, especially if the spots are totally uncreative,
boring and repetitive. Sometimes stations play the same spot twice during a
single set! How effective can that be to that customer?

Radio has become ridiculously redundant.
