It is now known that "Veer-Zaara" has music composed by the late Madan Mohan and sung by Lata Mangeshkar.

The prolific composer had scored some of the best and the biggest hits from the early 1950s to the late 1970s. Some of his golden compositions include songs like "Aap ki nazron ne samjha" ("Anpadh"), "Kaun aaya mere man ke dware" ("Dekh Kabira Roya"), "Woh bhooli dastan lo phir yaad aa gayee" ("Sanjog"), "Naina barse rim jhim" ("Woh Kaun Thi?") and "Ab tumhare hawale watan saathiyon" ("Haqeeqat").

The tunes were selected from his unused collection. The 30-year-old music was recreated by Madan Mohan's son Sanjeev Kohli. Before this, R.D. Burman's unused compositions were used after he passed away in "1942 - A Love Story".

Besides the evergreen Lata, Jagjit Singh, Roop Kumar Rathod, Udit Narayan, Sonu Nigam and Gurdas Mann have sung the songs with lyrics by Javed Akhtar.

Yash Chopra has even created a commentary for a track in the film a la Amitabh Bachchan in the song "Yeh kahan aa gaye hum" ("Silsila").
