Kal Ho Naa Ho - Nikkhil Advani . Let's first thank @shankarehsaanloy for this album, for this BGM. Kal Ho Naa Ho is not same without this music. A guy loved a girl, she also loves him but he is battling with life and knows he's going to lost that battle, but his love is true and pure so he wants to make sure that she will remain happy throughout her life, without him. . Is it simple to love someone when you know that you are not going to spend your life with him/her. Also at the same time from Rohit's perspective, he knows Naina and Aman loves each other, he respects Naina's feelings and he knows he shouldn't come in between them but he has to. This whole plot sounds little complicated but it's not. . I absolutely love SRK as Aman and Saif as Rohit, but Naina's story is little heavyweight than these two, her father attempted suicide because he's unable to deal with the guilt that he had a extramarital affair with a woman and she left him and their child then Jenni (Naina's mother) adopted her. On the other hand she loved a guy who is not able to spend the rest of his life with her. . Thanks to KJo's and Niranjan Iyengar's writing we can feel all these layers of each and every characters, because from Aman to little Gia everyone is having one or other issue with life, everyone is suffering, Aman is dying, Naina having her own personal problems, Rohit loves Naina but don't want to come in between her and Aman, Shiv (Naina's brother) is handicapped, Gia is feeling neglected by her own grandmother. Still despite of having so many complex issues KHNH still manages to bring a smile on our face because "Listen, live, be happy, smile… who knows if there will be tomorrow."
