The Punjabi song is actually really old. Indians love hip hop so only a little after Busta Rhymes came out with Fired Up someone (maybe punjabi mc) remixed it with an old punjabi song. I personally it's a poor attempt at rapping over the tune by Jay-Z, I really expected something more from him. On the other hand it's nice to hear punjabi music getting more airplay and it would never have made the airwaves without the rap. If someone is interested in the original song, let me know , I should be able to dig it up. by the way, the style of punjabi song that is sampled is called Bhangra.
