Victor Hugo, the French novelist who wrote Les Misérables and The Hunchback of Notre-Dame said "Music expresses that which cannot be said and on which it is impossible to be silent."
I think the essence of this beautiful quote is that music is a language unto itself. One that can generate emotional responses that are unattainable by means of the written or spoken word.
At the end of day, everything you and I are interested in revolves around this unspoken language that touches each of our souls.
Music.
