Warning: No-window-shattering zone ahead

I've never understood why some drivers feel the need to crank up their music to maximum volume.  Not only is it distracting to other drivers and ear-splitting to other passengers in the driver's car, but the music itself becomes distorted and difficult to listen to.  A former co-worker said he once applauded when one driver's loud music shattered the car's back window.  I can't say he was wrong to react that way.
