Loud or rock music not only causes accidents but also causes headache and strain. Soothing music is always good for relaxation and there are people who switch on Fm music in car while they travel to keep themselves active so they don't start sleeping while driving.The problem is the kind of music you choose to listen. There are many people who like listening to loud music and this is also one of the major causes of accidents in many cities. This is why I believe that music is bad for us.
