I listened to the songs. I was so surprised and shocked. Music is fresh. I am sure the director must have asked Deva to score 2 in ARR style 2 in HJ style and 2 in YSR style. There is no reference to IR or Deva or here.
There is one remix song that Deva did really well. Its the old song "Engeyum Eppodum Sangeetham Santhosham" by MSV. Deva did very well.
The album is worth listening/buying.
