"'Prem Ratan Dhan Paayo' is the most-awaited film of the year and I have tried to live up to the expectations of Sooraj ji's script and Salman bhai's persona, which is historic," Himesh told PTI in an interview.
The musician said he has composed nine "purely romantic melodies which are very soulful and yet have Salman Khan's stamp on them."
"Prem Ratan Dhan Payio", also starring Sonam Kapoor, not only reunites Salman with director Sooraj Barjatya after 16 years but also re-teams the superstar with Himesh after 2011's "Bodyguard".
Himesh has earlier composed music for Salman's films, including "Maine Pyaar Kyun Kiya?", "Dil Ne Jise Apna Kahaa" and "Hello Brother".
When asked about the recent trend of filmmakers making actors sing in their movies, the composer said he has no issues with it.
"If actors are singing well and churning out hits then I think it is a beautiful trend. There is no harm if it's converting into success, like in the case of Salman bhai," Himesh said.
The 41-year-old singer will also be seen as one of the coaches on singing reality show "The Voice India".
"I chose to be a part of 'The Voice India' because of its overall concept of blind auditions... and battles which is very unusual and also because this show has worked universally with the audience (sic). So far, I am loving every moment which I have shot for the show," he said.
According to Himesh, reality singing shows provide a great platform for new talent to kickstart their career, besides offering entertainment.
In the show, Himesh is looking for the talents who are fresh, unconventional and unique and he does not want voice which is similar to anybody in market.
"I am looking for voice that will have its own individual quality and style," he added.
Himesh said he will share his experience with contestants and guide them on their performance.
"Bookish knowledge does not work in the practical field of shows, performers and film industry. I will train them (contestants) in becoming super-performers, who are great singers with superb pick-up sense, besides having a quality of spontaneous audience interaction in them (sic)," he said.
The "Voice India" goes on air on TV from June 6.
