No body has analyzed music the way you have. i think your write up is about the best i have read in a long time as regards music. Different music gives you different feeling and satisfaction. And sometimes our moods determine the kind of music we would want to hear at that moment ...at least it works that way for me.And it gives me deep satisfaction. when am sad i want to hear slow,soulful and deep songs,when am happy and excited, i want to listen to a song i can dance and jump about while singing. Anyhow, i love music at lot.
