When the stresses and pain o life overwhelms us, a continuous string of songs help alleviate our sufferings. It is in the listening and absorption that hormones dance to tunes that stimulates life in the body to a more accepting condition of existence.
It works through the ears and rests the eyes and other sense organs. It has a strange way of growing on you. Like a bunch of vines on a tree trunk.
But when the pain is acute songs may cause distress. Chronic pain responds best to music.
