Playback Singer Kunal Ganjawala, known for his songs "Hum dum suniyo re" and "Bheege honth tere", says in a couple of years the concept of hiring one composer for a film would become a thing of the past.

Making his Bollywood debut with the song "Deewane aate jaate" in "Ab Ke Baras", in his over a decade-long career Kunal has worked with a host of ace music directors like Anu Malik, Pritam Chakaraborty, Himesh Reshammiya, Ismail Darbar, Shankar-Ehsaan-Loy, Anand Raaj Anand, Roop Kumar Rathod and Daboo Malik, among others.

"I feel that in a couple of years there will be no place left for single music director. Now, each person will make his own music, either by taking it from someone or by releasing own album or films with four-five music directors.

In films, this is already a trend, " said the singer at the DVD launch of "Success Profiles: The Anatomy of success" by Rakesh Sinha here Tuesday.

Kunal, a talent discovered through singing reality show "Sa Re Ga Ma", however, feels, music maestro A.R. Rahman is an exception.

"Except from A.R. Rahman and a few other music directors, every film has at least five music directors and it is a natural progression, if you see the West, because we only copy the West, " he said.

Talking about the film content, the singer feels filmmakers Vishal Bhardwaj and Sanjay Leela Bhansali are trying to add variety by adapting books into films.

"I am very happy that some directors are now adapting books, novels for films, like it happens abroad. I feel we can achieve variety only by adapting books. It's good that filmmakers like Vishal, Anurag Kashyap are bringing in this trend.

"Vishal kind of started it with 'Maqbool'... he is adapting a lot of Shakespeare's work, which is fantastic. Sanjay Leela Bhansali made 'Saawariya' based on a short Russian story, " said the singer who had sung two songs - "Pari" and "Maashah Allah" in "Saawariya".

Besides Hindi numbers, Kunal has lent his voice to Kannada, Tamil, Telugu, Marathi and Bengali songs as well.
