Music, much like food is major part of our lives and is ingrained in our culture. To many of us we use it as a form of art, a form of consulate from a breakup or motivation to work out or work harder. There have been plenty of times I have used music to pup myself up for job interview and get the nervousness out of my system.
Ah yes. Another person who sees it as I do. I believe that music gives us all a bit of catharsis when we need it.
