Music connects us with our inner selves and thee environment, when we hear music we let go of our thoughts so they can be whatever they want to be, this lets our creative juices flow freely. Our minds become more visual, more expressive and most importantly more free!. In essence music has the power to overcome resistance  and when there's no resistance nothing interrupts your train of thought.
Always remember that poetry and music make your heart smarter than your brain. Research shows that the broca's area of your brain is used to express music and that specific area enables us to produce speech and that is not a coincidence because in the past music was considered to be a form of communication.
Music also improves memory, attention and mental development.
