wow i can go on for hours. Music has helped me through some rough times, ska calms me down, makes me realize that things usually aren't worth the effort it takes to be upset over. Punk helps me vent any anger and frustration i have. Blues, oldschool rock and funk are all great any time, there so much soul there. Aside from all those obvious things though, you should look into the physical affects of music. there are AMAZING studies. Look up a test where they had rats run a maze, some after listening to classical music, and some after listening to hardcore. very interesting stuff. I think though, musics greatest aspect is that it will always be a friend to you. No matter what happens, there will always be music to help you feel your not alone, or if nothing else, to distract you, and give you a break from whatever you're going through. No matter what happens to the world, the music you love will always be great.
