outstanding background score

I love the background Score, especially when the words "zindadi kahe sataye " plays in the background.  I would love to find the actual song.  Then the tune that plays when Shraddha and Anand's interaction scenes are going on.  

yaah...i even humming , keep humming that melodious sound...''kaaahee sataye zindagi...''😃

yeah that song is amazing...somebody plz post it if u manage to get it!!!
