The Feelings

When you listen to music, how does it make you feel? The truth is probably that it isn't music that makes you feel a certain way, every type makes you feel differently when you hear it. I have realized that every time I don't like how I am feeling, I listen to or sing a song that will make me feel the way I want. It kinda explains why I have such a variety of songs on my ipod. And it makes me wonder, why does music make us feel a certain way? Do we like music because of the feelings it gives us? Comment if you have any theories.
