DSP a copy cat ?

The social media is busy with postings that Devi Sri Prasad has copied tunes for the new movie Janata Garage. The people who are posting these songs are also giving the base songs from where Devi copied the tunes.
Three songs copied they are saying. During the launch of audio of Janata Garage the hero of the movie Junior NTR claimed that it was a fantastic music and also thanked movie. But the reality is that the songs of Janata Garage are similar to some movies earlier made. It is does not look fresh and entirely new. There are similarities of tunes of some old and recent movies. There is no doubt about it.
But the reality is that some times, it all depends on the director and producer of a particular movie. If they insist that they want a song of this type or that type, the music director will have no choice but to follow the old tunes and get inspiration and it looks like a copied tune. They call it as inspiration.
