Gian Carlo Menotti, composer of "Ahmal and the Night Visitors", was asked how he came to compose such a wide variety of music. His reply was that he had never composed any music, rather, he had just listened attentively and had written down what he heard. Other great composers have made similar remarks indicating that the music is already there, and their task was only the writing down of it. There is an astonishing amount of research on the effects of various types of "music", which most people ignore if they even know it's there. The reason? They don't like it's implications re the stuff they choose for listening. The same filter they apply to news, politics, and history, they also apply to music. Certainly, we have the "right" to ignore the facts when forming our opinions,but if we look at the world around us, we see a lot of unnecessary chaos results. The problem arises when we begin to believe our own PR and believe our opinion is fact, resulting also in closed threads. Poor listening choices, like poor food and drink choices, can not only negatively effect our health, but damage and impair even our ability to think clearly.
