Shamshad Begum was one of the top singers in the fifties and sixties and went on to sing under OP Nayyar right until the seventies in films like Kismet ( Kajra muhobbatwala) and a few other films. But Salma Agha was nowhere near any of these singers since she went off key, so naturally faded away !
Some of the very beautiful songs that Mubarak Begum has sung and the ones I particularly like are Neend ud jaaye teri chain se sonewale, a duet with Lata Mangeshkar and Chah karni thi chah kar baithe again a duet with asha Bhosle , Zara kehedo fizaon se with Talat Mehmood and Mere aansuon pe na muskura a solo composed by Dattaram..
