The advent of radio, and then worse yet, TV not only supplanted homemade music as a passtime, it has distanced amateurs from the idea that their music is valid, to themselves and to others. Like that line in Playing Real Good for Free says: "Nobody seemed to hear him, tho he played so sweet and high, They'd never seen him on their TV, so they just passed his music on by."

On the other hand, TV's don't kill music, people kill music. There is nothing but mental laziness to keep one from enjoying a movie, or documentary, and THEN making music, nothing to stop people from abandoning the hum of their air conditioner and sitting on the front porch in the evening and strumming on the old banjo...except maybe for the sound of a leaf blower being used next door.
