"When one monopolizes the stages and media it is not good but songs themselves are harmless"

Good grief. The Smothers Brothers Show was an hour a week 40 years ago. Pete Seeger's tv appearances were probably less than 100 over his lifetime of 90 plus years. Their radio appearances and recorded music are similarly minute, comparatively speaking. Pete wrote a column for Singout magazine, read by a limited audience. What, exactly, monopoly are you talking about?

Consider the songs "We Shall Overcome" and "Joe Hill." Explain why they are without power.
