Senthil,
Fully agree with all your views. As I said Raja is adjusting himself to the new commerce of film making and film music but it is impossible that he will let anyone meddle with his music. He will patiently hear what the director / producer wants but once he has composed no one, including him, can change a single note. That is what M G Sreekumar told in an interview.
"In cinema everything should serve the purpose of story, character, actors, aesthetics and artistic style. Everything else is gibberish. I think Raaja has very deep understanding of this basic aspect."
Absolutely. Plum calls this narrative integrity. Raja will never get away from this path. That is my assessment. Even though he may be very flexible in external stuff, like attending CD release functions or praising the director etc, when it comes to his craft, he will maintain that integrity. Unfortunately the whole movie industry has moved from 'music should be integral part of the film' to 'music should be album based and caller tune based' !!!
