Who is the music director of Vijay - AR Murugadoss' film?

Its merely been days since the first look of Vijay's 61st movie Mersal has been launched and news about his 62nd film have already started coming up with new updates. Buzz in the industry about this upcoming AR Murugadoss directorial suggests three different names for the music director alone. 

Initial talks about Vijay 62 suggested that GV Prakash would compose the music of this film. It surely did surprise many as the director usually prefers Harris Jayaraj for his film's compositions with the exception of Kaththi. However, sources close to the team of Vijay 62 claim that Murugadoss is keen on roping in an already proven combo; in this case either Harris - Murugadoss or Vijay - Anirudh. While Anirudh's first time with AR Murugadoss and Vijay proved to be a chartbuster, Harris has been a regular in AR Murugadoss' movies and is currently keeping the audience expectant of their upcoming project Spyder. Who among these three will sign the dotted lines is something we will have to wait and watch.
