कल रातें

Kal Raatein — 'Yesterday's Nights' — is the most experimental song in the Bobby Aur Rishi Ki Love Story (2025) soundtrack, composed and sung by Sneha Khanwalkar alongside IP Singh. Khanwalkar, known for her groundbreaking work on the Gangs of Wasseypur (2012) soundtrack and her experimental approach to Bollywood music, brings a distinctly different sonic palette to the album — more ambient, more textured, less conventionally melodic than the album's other tracks. At 4:49 minutes it is the album's longest song.

Sneha Khanwalkar's production for Kal Raatein is ambient and enveloping — she builds a sonic landscape that evokes the specific texture of nights spent remembering. Her approach is far from the mainstream Bollywood sound: there are no conventional string arrangements, no soaring melodies, but instead layered synthesizer textures and atmospheric production that creates emotional space rather than melodic argument.

Khanwalkar's own lyrics for Kal Raatein work with the image of 'yesterday's nights' — nights as repositories of memory, as spaces where the past remains vivid. The plural 'raatein' gives the title weight: not one night but accumulation, pattern, habitual remembering.

Sneha Khanwalkar's inclusion in the Bobby Aur Rishi Ki Love Story soundtrack — alongside A.R. Rahman, Ashish Chhabra, Shaan, and other composers — suggests director Kunal Kohli's ambition to build a soundtrack of diverse musical personalities. Khanwalkar's track is the most experimental element of what is otherwise a mainstream romantic album.

Kal Raatein is the element of the Bobby Aur Rishi Ki Love Story soundtrack most likely to interest music critics and experimental listeners — it represents Sneha Khanwalkar's continued evolution as one of Bollywood's most distinctive compositional voices.
