Good point. The average use of radio is just over 19 hours a week by the
average American. That is a little over 2 hours a day, so the repetition is
not going to be at all noticeable.

But there's been some research that people only really want to listen
to a song 15 times or so, and the peak is at about the fifth hearing,
after that their enjoyment of it drops way off. (New Scientist,
about 5 years ago).
