There are many and it would be unfair to single out one to head the list. Right from Naushad to Salil Chaudhary, Shankar-Jaikishan, Roshan, SD Burman & RD Burman Jaidev... But no place in my list for A.R. Rehman. I don't care much for his music. He was selected by the West for political purposes and you know what I mean, since then with their herd mentality, people have started calling him 'great' , 'king' etc.
