Secret superstar by amir khan zara

Sometimes the voices don’t know speaks heaven than the voice I know.
I don’t speak Indian language but there are voices which speaks melodies I don’t understand but cuts deep into my heart
This song I rank it the best ever besides you perception about it, I don’t understand what’s behind the scene but what I know it’s still remain the best

Briefly let me describe this song as the song that makes angles a life, gives life to the dead and heals the wounded hearts
I wish you could tell the meaning of this song
