Badlapur is unusual terrain -a revenge drama with a sinister ambience that ordinarily would have left no scope for music. But the “90-minute love manual“, as producer Dinesh Vijan of Maddock Films prefers calling the album, organically blended music into the narrative. The album includes Jeena Jeena that teaches you how to fall in love, Judaai that brings out the pain of losing your loved one and the climax track Jee Karda that encapsulates the aftermath of the loss. We hear, each song materialised in a record time of 90 minutes.

Not meandering much from the tradition of Sriram Raghavan's films, the revenge drama uses songs only in the background. “Music works well when it has an absolute synergy with the story, which became the case here,“ reasons Sriram. Over their past four associations, composers Sachin Sanghvi and Jigar Saraiya discovered an alluring chemistry with Dinesh. “We come from the school of thought that believes music happens. A session of jamming, discussion and laughs later, we invariably have a song. The reason why not a single person has been credited for the lyrics is because we all have sat together, pooled in ideas and penned the final words,“ says the producer.

Sachin-Jigar say that Dinesh's taste of referencing is international. “For instance, we could make Jee Karda as raw as we wanted and the guts come from Dinesh's backing,“ says Jigar.

Mixing an interesting blend of singers, the composers concede that it's their patience that has paid off. “We waited six months to get Rekha Bhardwaj and Arijit Singh together for the first time for Judaai. We knew that their voices would make the song unforgettable,“ recounts Sachin.

For Jee Karda, they needed intensity and Divya, who sang the scratch, became inseparable from the track.“We needed honesty for Jeena Jeena that required less singing and more soul.Atif Aslam rendered it impeccably . The part of the song where he hums, it almost seems he is the guy sitting in your living room and crooning,“ says Jigar.

Gaining momentum is the bonus track Badla Badla, which is Sachin's favourite.“It's a battle between Vishal Dadlani's devilish voice, the coldness that Priya Panchal pulls off, the unpredictable depth of Suraj Jagan and the haunting quality of Jasleen Kaur Royal's voice,“ says Sachin.

Badlapur is a special album for Varun Dhawan, who treads out of his comfort zone with this project. Jee Karda is the closest to his heart. “I first heard it in Sachin-Jigar's studio and thought of it as an unusually cool song. Divya has sung the hell out of it. That song captures the essence of the film,“ says Varun.

Contrary to Varun's choice and his own role, Nawazuddin Siddiqui picks an atypical favourite. “I am a sucker for romantic songs and Jeena Jeena just blew my mind.“

Badlapur, presented by Eros International and Maddock Films, releases tomorrow.
