Constructive, distructive or destructive music?

Once in a while, I use public transport within my city to travel to different regions or commute home either from work or some business in town. We happen to have no shortage of public vehicles except at peak hours. However, one of my biggest setbacks is the kind of music allowed and played in some of these public vehicles in a bid to attract customers. In some of them shortly after they fill up with passengers and set off the drama begins. The music is played so loud that the seats literally vibrate. I wonder. Where is the respect for our senior citizens or even the passengers who cannot bear the noise? Our concerned authorities need to do something and urgently.
