With little success in acting, Mangeshkar went on to make a career in singing. She was initially rejected as a playback singer. However, she went on to deliver some of the industry’s biggest hits. Her first Hindi song was “Mata Ek Sapoot Ki Duniya Badal De Tu” for the 1943 Marathi feature, ‘Gajaabhaau.’ There was no turning back since. She went on to collaborate with Bollywood titans like Shankar Jaikishan, Naushad Ali and SD Burman, among others.
