I was little surprised when Amanat was singing this song, the credit for the original song was shown as Film: Masoon, Music: RD Burman, Singer: Lata Mangeshkar.
This song has both male and female versions in the film with male version sung by famous Bengali singer Dr. Anup Ghosal.

The first antara (stanza) of the song sung by Lata and Anup Ghosal is same (jeene ke liye socha hi nahi, dard sambhalane hoge) which Amanat sang. Since Amanat was singing the song, the male singer's name instead of female singer's should have been shown. Don't you feel so? I think many people do not know that Anup Ghosal sung the male version of the song and he sung it equally well. His name should have rightfully appeared in credits.
