Hello soulsistashakti, how this works got something to do with 'Naad' the holy (silent sound) vibration within the mind that is created by listening or singing along with devotional music or chanting. When music has this devotional intention and the right sound vibrations to go with it, then we get in touch with this Holy vibration inside our minds which blocks out all other cacophony, inside noise in our minds and brings us to silence. Take a look at my post about the Gayatri for Goddess Lakshmi.
