Love of music

Now they say it's because of some hormone secretion that we love music so much. But isn't it something beyond that? At the root of it, there has to be some unanswered facts for which we love listening to that rain drops.. that sound of wind gusting through bamboo leaves... there has to be something beyond hormones for which we love music..and that I certainly have experienced myself.
Music is everywhere. Hindustani classical music has evolved deep from vedic chanting...and influenced by sounds of nature. Flowing river, whistling wind..all have contributed equally on evolution of music.
