I listen to it usually when I need to change my state of mind. I really started listening to music while in middle and high school art class. Showing my age, I then had my sony walkman while skateboarding. Later it was a diskman. Then it was in my car for long trips. I had an mp3 player while deployed over seas in the military. I listen to music to get motivation for my workouts. I go to rock shows whenever possible to forget about the stressful workweek. Getting smacked around in a mosh pit is icing on the cake, (but i'm getting to old for that now).
Music just really helps me focus, get fired up, chill out or create a distraction. I tinker around on guitar because of my love for music.
