One of the most popular composing groups, Shankar Ehsaan and Loy have been behind some of the most successful soundtracks in recent times. They shot to prominence with Dil chahta hai and later gave smash hits like kal ho na ho. In 2001, they made their film debut in Tamil film industry, as Kamal Hassan signed them to compose for Aalavandhan. The music sold well due to the hype surrounding the movie, though the movie itself was a dud in the box-office. The turning point of their career as music directors though, was Dil Chahta Hai, which was the debut film of Farhan Akhtar as a director.
