Conventional ?melodies? were replaced by experimental music, as Bollywood became ?cool?. 2000 The end of ?melody? Nadeem-Shravan had cracked it. The ?90s had belonged to the composer duo, who churned out chartbuster tunes, one album after another. After a brief hiatus, the duo had come back to Bollywood in 2000 with Dhadkan. Almost instantly, the music created new records. But with Taal in the last year, A R Rahman had proved that conventional Bollywood melodies were giving way to a new sound ? where experimentation would lead the way. The dawn of music directors like Vishal-Shekhar and Shankar-Ehsaan-Loy on the scene, who gave equal importance to music production, as they did to composition, all signified a complete overhaul of ?conventional? Bollywood music.
