Music can do something.. change lives, give hope. It can make anything better in life. it even sometimes gives life meaning. I would not be where I am today without music. I don't play anything or sing. It helps me live, when I have those thoughts it makes me feel less alone in what every is going on.
You can create friendships by just talking about music, wearing your favorite band t shirt and someone could come u to you and say, "I like them too."
Its also a way to tell a story. sometimes it will make you cry. sometimes Happy, and sometimes numb. We all need to have tears to have the happy and meaningful times.
