Humma Humma song is too good not only for party time but also for suggesting someone.Another songs is the title song music by A.R.Rehman.In the lead role is Shradha kapoor and Aditya Roy Kapoor playing cute roles in the movie.Only two songs are released till now.If you grew up in 90 s I m sure u prefer the original track instead of this.Singers of the song are Jubin Nautiyal and Saasha Tirupati.Rap is also included in the song sung by Badshah which makes the song more attractive and enjoyeable.
