A.R. Rahman has done it again! After ‘The Humma Song’, the title track of OK Jaanu just released and we are loving every bit of it. It's a revamped version of the original song ‘Mental Manadhil’ from OK Kanmani. Mr. Rahman has beautifully sung this one along with Srinidhi Venkatesh. His music, along with Gulzar’s lyrics, have created the magic yet again, the same way that it did in Saathiya. Aditya Roy Kapoor and Shraddha Kapoor are seen exploring South Mumbai in the video and their chemistry is amazing! We can’t wait to watch them together onscreen. The song is super fun and we are already playing this one on repeatand eagerly waiting for more such songs by Mr. Rahman… For now, you guys have to watch this one and fall in love with it. Here, have a look.
