The well-known later playback singer, Lata Mangeshkar, started singing when Begum was at the peak of her career, with Begum's break after her husband's death boosting Mangeshkar's career and helping her get offers for high-quality songs. In the early careers of Mangeshkar, as well as her younger sister, Asha Bhosle, between 1944 and 1956, they had often been asked by producers and music directors to imitate Begum's style of singing, because producers could not afford Begum's fees. In their first song together, Mangeshkar was a part of the chorus while Begum was the main singer. Many of the songs sung by Lata like ""Ayega Ayega"" were sung in Shamshad Begum's style. Even Asha Bhosle's songs like her first duet with Kishore – ""Aati Hai Yaad Humko"" from the 1948 film "Muqaddar" bear direct resemblance to Shamshad Begum's style. From 1949 to 1960, beginning with the song "Dar Na Mohabbat Karle" from "Andaz", Mangeshkar and Begum have sung many duets together, with the most famous being "Pyar Ke Jahan Ki" from the 1949 film "Patanga", "Bachpan Ke Din" from 1951's "Deedar"; their last song together was "Mughal-e-Azam"s song "Teri Mehfil Mein Qismat" in 1960. Begum sang songs together with Mangeshkar and Bhosle, including "Mubarak Ho Woh Dil Jisko" from "Benazir" . It was between 1958 and 1963 that the career of Lata got a major boost as music directors started gradually preferring her soft voice. Until then, Geeta Dutt and Begum were the most preferred singers, but Shamshad Begum continued to be at the top from 1940 till 1963.
