I see someone already largely answered this. Here's a little more:
"The Sound of Silence". The lyrics:
For the words of the prophets were written on the subway walls.
Tenement halls echo with the sound of silence
"The Spirit of Radio" lyrics
For the words of the profits were written on the studio walls
Concert halls echo with the sound of salesman.
The Spirit of Radio is Neil's rage against blatant commercialism in music.
