लो डूब गया ख़ुर्शीद

Feroze Nizami trained in classical music under Ustad Abdul Wahid Khan of the Kirana gharana and came to Bombay from a singer's post at All India Radio; Piya Milan is one of only two scores credited to him in 1945, the other being Sharbati Ankhen. Rajkumari sings this and nothing else in the film - one of five singers Nizami used across eleven tracks, none of them doubling as a chorus.

Khursheed is the Persian word for the sun, and choosing it over the everyday suraj pitches the line towards Urdu poetic register rather than colloquial Hindi. A sunset announced with 'lo' - behold, there it goes - is the classic ghazal gesture of pointing at a loss as it happens. M. Naseem wrote the words. MySwar transliterates the title as 'Lo Doob Gaya Khursheed'; hindigeetmala's spelling is followed here.

Piya Milan (1945) was produced by Wadia Movietone and directed by S. M. Yusuf, with Motilal as the male lead and the eighteen-year-old Nirmala Devi as his leading lady. Wikipedia's list of Hindi films of 1945 classes the picture as a social, and the surviving record catalogues agree on an eleven-song album, every number composed by Feroze Nizami. No print of the film is known to circulate, so the songs and their credits are effectively all that survives of it. The song is documented in both hindigeetmala's and MySwar's track listings for the film, which agree on its singer and, where one exists, on its lyricist.

Rajkumari was among the busiest female playback voices of the 1940s; this track is a minor entry in that run and no separate notice of it has been traced.
