The rich guys have known for thousands of years how music can be used to make people march to their tune. Aaron, they are a lot more sophisticated at that trick now. I don't trust any of the mass media's music. I trust my own music that I compose as I blow into my little old harmonica. I can blow music that makes me happy or that makes me sad or that makes me feel peppy.
Music is a very powerful mind-conditioning force used on everyone who absorbs the mass media.
Besides that, they probably have subliminal implants in their music that may be making us believe that we are not slaves and causing us to believe lots of other untruths. I do agree with you that we need to express our feelings about the bad things that are in the System. And get angry too. That is good. But not to linger and lounge in anger.
