How many songs do we know about radio, listening to the radio, etc.?
Here are the ones I can find whose lyrics have already been posted at Mudcat:
GOD'S RADIO PHONE by Wade Mainer
HEAVEN'S RADIO by the Carter Family
I HEARD IT FIRST ON THE RADIO by the Gaither Vocal Band
MOHAMMED'S RADIO by Warren Zevon
ONE HAND ON THE RADIO by Aengus Finnan
RADIO FRAGILE by Nanci Griffith
RADIO LADY by Andy Roberts
RADIO STATION S-A-V-E-D by the Blue Sky Boys
SINCE WE PUT A RADIO OUT IN THE HENHOUSE by the Hoosier Hot Shots
STATIC ON YOUR RADIO by the Poozies
TEN-POUND RADIO by Jerry Rasmussen
THE OLD RADIO by Pine Mountain Railroad
THEY DON'T PLAY OUR SONGS ON THE RADIO by the Wolfe Tones

If you post a title that broadly fits the category of "songs that some Mudcatter might like to sing" I might look it up and post the lyrics here.
