I think Khuda Jaane is the best choice as it suits all 3 couples very well. The words of the song are really suited for the love all 3 couples share.For me whenver I hear the song it feels as if Sharad is singing for Divyanka or Sagar for Vidya and even Amar for Divz.If you are planning a vm for them I would love you to make it on this song. I do not know how to make vm's but if I did this would be my first one!!
i know that sweety thats why i referred this song
