Perhaps not 'DX' in the true sense, sans loop antennae or a headset and a Vane A Jones logbook, but ones to come to mind:
'Pilot Of The Airwaves' by Charlie Dore. It's essentially the Joni Mitchell song 'You Turn Me On ; I'm A Radio', sideways. Both are neat tunes.
The Mitchell song, of course, is from where those lyrics came: 'Who needs the static? It hurts the head.'
The incredibly underrated Michael Stanley Band, from Ohio, had at least two songs on the subject. One of them, a decidedly Springsteen-ish thing called 'Lover' -- complete with Springsteen's own sax player Clarence Clemons -- mentions 'the news at the top of the hour, which no one really believes'.
(There is another radio reference in that fine blend of melody and poetry about weary and lonely nighttime driving, too. But the best line is 'Thank God for the man who put the white lines on the highway').
And in their rockier 'All I Ever Wanted', perhaps a definitive MSB tune of more recent vintage, he sings about things like 'turn up the radio, til this one's through' , and 'The Dee-troit station came screaming'.
Gosh. I wonder which station he meant?
Perhaps fatefully, Stanley now does an air shift at classic-rock WNCX in Cleveland.
