Someone was saying - Now I know why my NaNa ji and Grand Father used to listen to K L Sehgal. The songs of their young age time, It is a therapy. It cures you, It keeps you hopeful, active, peaceful. It brings the memories of that time in front of your eyes. Nobody has time to ask them and listen about their childhood and young age, their struggle and success story. So the old songs are alive till today.
Music of your liking keeps you Cheerful and Healthy.
Some songs help for recovering from grief and sadness.
