Why Bala did not sign up Yuvan for his next?

Yuvan Shankar Raja and Ilayaraja have always been director Bala's choice to compose music for his films. However, for his upcoming movie, the director has decided on GV Prakash.

When Yuvan was questioned about this, he had said that Bala wanted all the songs for the film within a week and he was not in a position to do that due to prior commitments. The music director said that the decision not to work together for this film was mutual and there were no hard feelings from both the sides.
