Chaiyya Chaiyya comes from the 1998 Bollywood film Dil Se, composed by A. R. Rahman with lyrics by Gulzar and sung by Sukhwinder Singh and Sapna Awasthi. The song became famous for its sequence filmed on top of a moving train, featuring Shah Rukh Khan and Malaika Arora dancing to its pounding rhythm. Its repeated chorus and folk-inspired energy helped it travel far beyond the film, through television, stage performances and later social media edits. It remains popular because the hook is instantly recognisable and carries a sense of freedom, movement and celebration.
