Singer Mohit Chauhan has lent his voice to “Kaun Hai Woh” track from Huma Qureshi-starrer “Baby Do Die Do”.The track released on Monday and has been composed by Arjun Iyer with lyrics by Iyer and WB Sam.The song beautifully captures the blossoming love story between Qureshi’s Baby and Rachit Singh’s character, Siddhu.Chauhan, known for tracks such as “Kun Faya Kun” and “Matargashti”, among others, said the latest track has a “sense of curiosity and vulnerability”.”What I loved most about ‘Kaun Hai Woh’ is the mystery woven into its melody. It doesn’t tell you everything upfront; instead, it invites you into Baby’s world one emotion at a time… I hope listeners enjoy discovering the many layers of the track and the love it represents,” he said in a statement.The film is directed by Nachiket Samant. Also featuring Sikandar Kher, Chunky Panday, Rachit Singh, Marudha Shekhawat, Vidya Malvade, Arun Kushwah and Himanshu Malik, the film is set to release on July 3. It is produced by Saqib Saleem.
