Kedarnath Bhattacharya, better known as Kumar Sanu (born 20 October 1957), is a leading Indian playback singer of Bengali background, popular for rendering his voice in Bollywood movies of the 1990s and early 2000s. He holds the Guinness Book world record for recording the most songs in a day, 28, in 1993. He was awarded the Filmfare Best Male Playback Singer Award for five consecutive years. In 2009, the Government of India awarded him the Padma Shri, India’s fourth-highest civilian honour, in recognition of his achievements.
Kumar Sanu started his playback career in 1986, with the Bangladeshi film Tin Kanya, directed by Shibli Sadiq. In 1987, music director and singer Jagjit Singh offered Sanu the chance to sing in the Hindi film Aandhiyan. Sanu had his first major Bollywood song in Hero Hiralal (1988).
In 1989, Jagjit Singh introduced Kumar Sanu to Kalyanji-Anandji at their residence Vimal Bunglows in Mumbai. On their suggestion, he changed his name from “Kedarnath Bhattacharya” to “Kumar Sanu” because his voice and singing style were much influenced by Kishore Kumar. Anandji shared this story on the show Jeena Isi Ka Naam Hai, hosted by Farooq Sheikh. Sanu then relocated to Mumbai, where Kalyanji-Anandji gave him a chance to sing in the film Jaadugar.
For the 1990 film Aashiqui, music directors Nadeem-Shravan got Sanu to sing all but one of the songs. He won the first of his record five consecutive Filmfare Awards as Best Male Playback Singer. His next Filmfare Awards came for songs in the movies Saajan (1991), Deewana (1992), Baazigar (1993) and 1942: A Love Story (1994). He won 5 back to back Filmfare awards for singing, between 1990 to 1994.
