Sonu Nigam (Bollywood/Pop)
Nigam is undoubtedly one of the best singers to have emerged from India. Apart from working in the film industry, he also has successful private albums (including Mausam, Deewana and Jaan) to his credit. His father, Agam Kumar, also a singer, guided him from childhood. "I have been singing professionally since I was four. Music is a by-product of a particular sense that many people don't perceive. I was born with that sense and thus, it came to me naturally," says 43-year-old Nigam, the voice behind hits like Main Hoon Na and Kal Ho Naa Ho.
