Prakash Jha seems to have given in to commercial constraints and added an item number to his political thriller Satyagraha. Buzz is that the acclaimed director has roped in model-actor Natasa Stankovic to groove to a thumri-electronic fusion number called "Aiyo ji hamri atariya mein" for the film.

The filmmaker believes that such songs contribute to certain sensibilities and add to the story.

"Such numbers contribute to certain moments and sensibilities. They (dance numbers) help the story too," Jha said in a statement.

Earlier, Manyata Dutt, wife of actor Sanjay Dutt, did an item song called "Alhad mast jawaani" for Jha's 2003 released film Gangaajal. Also, television actor Barkha Bisht performed to an item song titled "Ishq barse hai boondan boondan" in 2010 film Raajneeti.

"Manyata's song helped in establishing the psyche of debased people. In Satyagraha, the item song creates the ambience of affluence and the bonhomie of corrupt people," added Jha.

He also admits that peppy songs such as these help to draw attention to a film.

"They do entertain; and entertainment happens to be the most important part of filmmaking. At the same time, when used cleverly, they can also be meaningful," said Jha.

Natasa, who has previously shot for a few ads in India, is also excited about the number.

"In October 2012, I went (came) to Mumbai, where I started to do shows, TV commercials, billboards. My favourite job was my advertisement for Johnson's Baby collection...Now, I hope that the song will be a hit, and my game will come to the fore," she said.

Satyagraha stars Amitabh Bachchan, Kareena Kapoor, Ajay Devgn, Manoj Bajpai, Amrita Rao and Arjun Rampal and hits theatres next month.
