The "power" of music

I was driving to the library today with the 4 boys and the oldest two were arguing in the back seat. Since I was driving I couldn't deal with it and was in a bad spot to pull over. So, instead of giving them an earfull from the front about fighting, I just turned on some Children's Christan music. The arguing suddenly stopped and throughout the whole van 4 boys were singing praises to God and smiling at each other all the way to the library. Just like that! In my own experience certain music makes me feel peaceful and joyful and others make me feel stressed and irritated. It's pretty incredible...
