Music is a tool of sedation, once it gets stuck in your head, it basically acts as a barrier in your brain preventing logical thinking, preventing you from even thinking your own thoughts, keeping your natural vibrations down and creating neurological instability.
Think about, what good really come from music? NOTHING. For an example, examine "rap music", it's centered around sexual perversion and violence. That is what it's turning America into. Music puts a person into a trance, putting their thought processes into an alpha state (this is the most prominent part of hypnosis).
