Akon sang Chammak Challo in the Shah Rukh Khan-starrer Ra.One (2011)

It's believed that music bridges the gaps between countries. This holds true for several years of cultural exchange between India and Pakistan. A few years ago, many Indian filmmakers had started banking on popular international musicians for the success of their films’ soundtracks. While Thai pop sensation Tata Young sang Dhoom Machale for Dhoom (2004), American R&B singer-songwriter Akon sang Chammak Challo in the Shah Rukh Khan-starrer Ra.One (2011). Also, Snoop Dogg donned Indian attire and did bhangra with Akshay Kumar in Singh Is Kinng (2008). The rapper grooved to the tunes of the title song of the film. But there was a lull in the trend for a while. Now, it seems to be making a comeback. Several international artistes have started embarking towards Bollywood again.
