इस बदलती दुनिया में

A title-evoking philosophical number from Badalti Duniya (1943), sung and composed by the blind musician K.C. Dey for Mohan Sinha's Murari Pictures production. The song takes the picture's central idea — a world in constant change — and frames it as a moral reflection, the kind of grave, devotionally-tinged number that was K.C. Dey's specialty and that he typically performed on screen himself.

K.C. Dey composed and sang this himself — a slow, harmonium-anchored melody in his characteristic devotional-philosophical register, with a measured tempo that lets the moralising lyric breathe. His grainy, weathered voice carries the song's reflective weight without ornamentation.
