How to translate and analyze the Hindi song "Kal Ho Na Ho"

So we come now to learning Hindi through our first Bollywood song from the film "Kal Ho Na Ho" (title song), starring Shahrukh Khan, Preity Zinta and Saif Ali Khan. We have jumped to very advanced stuff, just to keep up the enthusiasm of my viewers, so I had to just hurry through everything in the 10-min. video. At first the devanagari writing and IPA pronunciation is given over the song itself, and later the song is analyzed. Its word-to-word gloss is given in English, followed by line-by-line meaningful translation.
