The entire music album of "Dil Bechara" is done by Rahman.

"Composing music doesn't have any formula, it is a thing of the heart. When I write songs, I let them breathe for some time and then present it to the director," Rahman said.

"It was a great experience collaborating with Mukesh Chhabra on this film; his enthusiasm is infectious. This whole album is carefully curated because the film has so much heart, and now, memories of Sushant. It was a pleasure to work with lyricist Amitabh Bhattacharya on this soundtrack of love. The songs are eclectic and feature an amazing lineup of India's top singers and musicians. I hope you will like the album," he added.

The entire music album of the film was released on Friday.

The soundtrack to "Dil Bechara" comprises a diverse mix of songs. The film's title track, sung by Rahman, is a vibrant celebration of life's ups and downs; "Maskhari" is a lighthearted song about friendship, features Sunidhi Chauhan and Hriday Gattani on the vocals. There's also Shreya Ghoshal and Mohit Chauhan's "Taare gin", "Khulke Jeena Ka" (an adaptation of Rahman's unreleased Tamil track "Kannil oru thali"). "Main tumhara" is sung by Jonita Gandhi and Hriday Gattani.

"Dil Bechara" is the official remake of 2014 Hollywood romantic drama "The Fault In Our Stars", based on John Green's popular novel of the same name. Budding actress Sanjana Sanghi stars opposite Sushant in the film. Casting director Mukesh Chhabra is making his directorial debut with the film.

Talking about the music of the film, Mukesh said: "Befitting the story of the film, its music album is an emotional rollercoaster of romance, friendship and the odds pitted against two young people in love. Having A.R. Rahman aboard for the music of my directorial debut is a dream come true. What's amazing about the genius of Rahman in this album is that it beautifies the narrative and takes it forward. I can only hope that the listeners enjoy it."

Sushant's last film "Dil Bechara" will premiere on the OTT platform Disney+ Hotstar on July 24.
