There is lots of criticism against Devi Sri Prasad saying that he copies a lot of tunes from other genres. Well, many music directors of present generation copy tunes from pop, Latin American tunes and it is quite common these days. And so is the case with DSP say some critics, especially those from Tamil industry. However, Devi Sri maintains that he never lifts tunes and adds that if a producer or director suggests that he has to copy tunes, he simply turns down their films.
Well, while DSP does not copy tunes, he surely copies his own tunes. In fact, the BGM of his earlier films is often used as music for songs in his later films. For example, BGM for Nuvvostanante Nenoddantana has been used for Pournami. There are several other such examples and it is pretty obvious to all those who had watched his films in the past.
