रहने लगा है दिल में अंधेरा

'Rehne Laga Hai Dil Me Andhera' belongs to the soundtrack of Roti (1942), Mehboob Khan's leftist drama about hunger and exploitation, with music by Anil Biswas. The film is historically notable for introducing Akhtaribai Faizabadi (later Begum Akhtar) to Hindi cinema as both actress and singer; her six ghazals were later withdrawn over a recording-contract dispute and issued on Megaphone records.

Anil Biswas casts this ghazal-leaning number as a duet, singing alongside Ashraf Khan — a rare instance of the composer lending his own voice to the soundtrack. Behzad Lakhnavi's verse sits over a restrained, melancholy accompaniment that suits the song's image of a heart darkening in the beloved's absence.
