Whatever the inventor intended, whatever the first backers meant, the real function of radio turned out to be to turn all music into noise. (Thanks to the rare FM station, it succeeded only 99.9%.)

CBS late night US Open Report, far too frenetic for years, is now hardly distinguishable from Top Ten stations that interrupt themselves with the song, the song with another song, the other song again with themselves. No margins, no room to breathe.
