Khan, who was in London on a brief visit to promote his latest film, told Reuters in an interview that while "Fan" had a theme song, it did not actually feature in the movie and had been used purely for trailers.
"The younger filmmakers and everyone, they know that, you know, we don’t need to just shove in a song anymore," he said.
"I don’t think it’s going to take away. It’ll take a lot of time to take the songs out of us, but every film will have a different requirement,” he said.
Bollywood films traditionally have had complex musical scores and filmmakers have rarely resisted the temptation to insert a song and dance sequence into a film. Some films' success rates have been dependent more on the music than the plot.
Khan’s latest film, which is being released globally on Friday, sees the actor playing a double role in which a lookalike fan is obsessed with a film star.
On Wednesday, Khan revealed a waxwork model dressed as the lookalike fan, Gaurav, at Madame Tussauds museum in central London.
When asked if he had ever met his lookalike in person, he said many fans often dressed like him.
"I'm a very common looking guy. I have a person who dresses up like me and they all wear dark glasses so they're kind of similar and they speak like me, in Kolkata. I have a boy called Prashant in Mumbai. I meet lots of lookalikes. Even on Twitter if you go, there's people who dress up. Before my eye surgery, I would confuse lots of them for my own pictures."
