Bollywood playback singer Sunidhi Chauhan says the Main badhiya tu bhi badhiya song for Sanju captures the era of retro music, and that it was tough for her to get the tone right. Its composers Rohan-Rohan say actor Ranbir Kapoor was quite involved in the making of the song.

Sunidhi told IANS: "My voice is different. I do not have that nasal voice. So I found it little difficult to sing, but that was the challenge I took". Composers Rohan-Rohan -- comprising Rohan Gokhale and Rohan Pradhan -- who have worked in the Marathi film industry, have made their Bollywood debut with the song Badhiya.
