Indian Industry is famous for copying movies from others who have spent enormous sums to produce them,there is nothing new that they have nothing original but thrive on copying and now this technique of remix its just ok.
Those who do remix argue that they are making the older songs more better & more of the present generation so that they will listen to the old songs.many times they make it too much artificial with too much techno music & beats for which it looses the originality.
