Great input... I got to thinking about my question, and it seems to me also, that perhaps the music became a bit too honest or true for the mainstream public. You are absolutely right when you hear "Music reflects the soul of Mankind!"..the truths of folkmusic were instrumental in change. Think about the protest songs, the freedom riders music, etc. Even the political jabs of music by the Smothers Brothers were too close to home for TV executives who yanked their show.
