Varun said, "Arijit did some 1200 takes for the Kalank title track. He requested one more, one more and this I know because I heard… how this song was made and the story behind it."

Just like us, even Varun Dhawan is highly impressed by the title track which is said to be the love anthem of this year. Praising Pritam who has given the music for the songs, Varun said, "That's Pritam genius ya. In the age of remixes, he came up with an original tune. Him and Arijit Singh, who has fantastically sung that song. He goes too deep while crooning the track. Earlier, I hadn't heard the complete song, but when you listen to the entire number, you forget about the music and are lost in Arijit Singh's melodious voice. He has such a powerful voice."

Kalank is a period drama set in 1945 during the pre-independence British era. The film stars an ensemble cast of Madhuri Dixit, Sonakshi Sinha, Alia Bhatt, Varun Dhawan, Aditya Roy Kapur, and Sanjay Dutt. It will hit the screen on April 17.
