Current Song on Replay

So I'm not sure if you guys have listened to the songs from the new film 'Karthik Calling Karthik' but I'm really liking one of the songs. It's called 'Jaane ye kya hua' ..I know I'm a little late with this one. I think it finallly grew onto me. What are your first thoughts of the song?

*ing: Deepika Podukone and Farhan Akhtar.
