Pop goes the film song as lyricist and poet Javed Akhtar and RD Burman-inspired composer duo Jatin-Lalit talk about what goes into a hit song. A few extracts: Akhtar: The song no longer takes the story forward, like it used to....Take the songs of Pyaasa and Kaagaz Ke Phool -- they cannot be written for Zinda Jala Doonga, they can only be written for Pyaasa. Touché Mr. Akhtar.
