Someones proposals concerning music

I heard, well actually i read about someone who proposed this statement: "Music and singing do not produce in the heart that which is not in it."

Actually I bet that person isn't a musician. Actually on the contrary, music makes the heart alive and restores the heart.

Here is another proposal by someone that I found interesting: "Those who are affected by music can be divided into two classes: Those who hear the spiritual meaning and those who hear the material sound."

I find that interesting for I hear both. The spiritual and the material. I wish that person would have written about the acceptions.
