The second song from Karan Johar's upcoming film 'Rocky Aur Rani Kii Prem Kahaani' was released on Wednesday. The song titled 'What Jhumka' features Alia Bhatt and Ranveer Singh grooving to the energetic number. The song uses the melody of the hit song 'Jhumka Gira Re' from the 1966 film 'Mera Saaya'. 

While people have had strong opinions regarding remix and remakes of classic Hindi songs 'What Jhumka' only uses the melody of the original song and part of the lyrics towards the end of the song. After the release of the song, music composer Pritam took to his Twitter handle to share why they have used the music from film of the 60s and 70s. "Karan has a very strong sense of music and knows exactly what he wants. For the Rocky and Rani background soundscapes, we decided to use 60s and 70s film music. In fact, the entire film is an homage to those great musicians and great songs—the music both of us have grown up with. This goes perfectly with the script and setup of the movie. Also, Saregama coming in as the music label and having the biggest catalogue of old film music made this dream of having a lot of retro re-invention in the film a cake walk," he wrote.
