As the title almost give us a full picture of what the song is all about. The saddest thing in life is to lose someone you love with your heartedly. NOT THIS LIFE is a song about all those who have lost their parents. Listen to this song as parents are the one's speaking . The whole morale of this song is to try convincing all those who have lost their parents that they're not alone even though this world can make them feel lonely. Among the stars their lovely ones always stand tall to comfort them.
