Yeh Dil Diwana Hai - Ishq Par Zor Nahin by Lata Mangeshkar, Mohammed Rafi

Some songs are made for a single moment. Yeh Dil Diwana Hai - Ishq Par Zor Nahin is made for all of them. The production by S. D. Burman is understated in the best way — supportive without overshadowing the vocal.

There are singers who perform songs and singers who live inside them. On Yeh Dil Diwana Hai - Ishq Par Zor Nahin, Lata Mangeshkar, Mohammed Rafi clearly belongs in the second group. The song is tied to Dharmendra, Sadhana, Biswajeet, Kamini Kaushal, Abhi Bhattacharya, Nadira Babbar, Leela Mishra, Jagdeep, Jagdish Raj, whose presence gives Yeh Dil Diwana Hai - Ishq Par Zor Nahin a visual dimension that fans of the film will always associate with it.

1970 marked the release of Ishq Par Zor Nahin, and Yeh Dil Diwana Hai - Ishq Par Zor Nahin was the track that ensured the album would be remembered. The song rewards full attention but also works as company in the background — a flexibility that most tracks never achieve.

Running to 4:45, the song is exactly as long as it needs to be, which is the hardest length for a songwriter to find. It is, at the end of it, a very good song — and sometimes that is the only explanation that matters.
