Lata Mangeshkar, Kishore Kumar inhabits this song completely, making every phrase feel like it was written specifically for this voice. The story told by Shashi Kapoor, Mumtaz, Rajesh Khanna, K.N. Singh in Prem Kahani finds its musical expression here — Chal Dariya Mein Doob Jayen - Prem Kahani is where the film's heart beats loudest.
