Do u guys know why ARR offered that song to HR? Actually in that movie the hero of the movie ran into accident and he lost his voice but somehow he manged to communicate through his nose. In the meantime he fell in love with heroine. After that there is song where hero sing a song for heroine. Since he cant sing through his mouth , he sings from his nose. Thats why ARR thought Himmesh is perfect singer to sing that song.
