The music of Shah Rukh Khan‘s film Dil Se played a key role in the success of the film. How can we forget the very famous song Chaiyaa Chaiyaa that was shot on top of a moving train. Chaiyaa Chaiyaa is famous for reasons more than sizzling Malaika Arora Khan. This song was the very first one that was filmed on top of a real moving train. Despite the fact that the train was actually moving, SRK, Malaika and all the dancers showed no sign of fear and danced out on the beats of the peppy song.
