We eat a variety of food so that our body has what it needs to repair itself and maintain its strength. It should be the same with listening to music.
Music has the power to manipulate us emotionally and the capacity to expand our intellect. It is a mixture of passion and order; beauty and logic. But like food, not all music is created equal. Ground beef is not better than sirloin. Michael Jackson is not better than Pyotr Ilyich Tchaikovsky. But we can’t just eat steak all the time. Sometimes you really do want a hamburger.
Have the discretion to not drink arsenic and anti-freeze. There is no Food and Drug Administration of music. Much of the stuff out there will rot your emotions and your intellect. Silence is much more constructive.
