A friend knows the song in your heart and can sing it back to you when you have forgotten the words Who knows the tune that my heart plays Because I can't hear the words my heart speak I feel lost inside my own world Can't locate where my heart is Inside my chest is cold below zero I'm losing the fight against sanity Slowly slipping back into depression Happiness is a foreign word that I don't comprehend So again Who knows the tune that my heart plays Who can restore my faith in myself I try but can't do it alone...
