AR Rahman's hit racy Humma Humma number from Bombay (1995), will be recreated in OK Jaanu. Aditya Roy Kapur and Shraddha Kapoor will be seen romancing each other in this track, which releases today. The song is Badshah's tribute to Rahman's original version. We hear that he sought the music maestro's permission before recreating the evergreen song with Tanishk Bagchi. Rendered by Jubin Nautiyal and Shashaa Tirupati, it will see Badshah rapping in it. He says, “I am equally excited and nervous, as working on an iconic A R Rahman track is a rare opportunity. I promise you that the song will be awesome with a completely new sound.“
