Salman Khan's upcoming film 'Kick' has been making headlines since the time of its announcement.

First, it was the film's trailer that garnered outstanding reviews and soon, the first song of the film, 'Jumme Ki Raat' was also loved by one and all.

And now, the makers have recently launched the audio of the second track titled 'Hangover' which is sung by Salman himself.

However, recent reports suggest that the song was initially recorded in Sonu Nigam's voice.

'Hangover' is a duet song which was initially recorded with Shreya Ghosal and Sonu Nigam. While Shreya's voice remains, the makers have edited Sonu's part and inserted Salman's voice instead.

We hear that Sonu had no idea about the change in vocals, until he read it in the papers.

The singer also confirmed the same stating, "Yes, I had recorded this song last year. I wasn't told that it has been dropped. I read it in the papers that Salman had sung it. I wasn't even paid for it."
