One of my uncles - the King of Kuchbinahi - ha therein lies a story so let me explain that before I continue. When I was in Kindergarten that uncle of mine solemnly told me that he was actually a King in disguise and I was never ever to reveal that secret. Naive little me swallowed hook-line-and-sinker and was told that the said Uncle's Kingdom was Kuch-Bhi-Nahin - that for my non-Hindi speaking readers means nothing, nada, zilch!!
Anyway my dear uncle began grumbling about how Carnatic music was meant for a certain mood and time and could not be enjoyed like pop-music when co-incidentally the very same thing began happening in the movie...
(Notes for V, R and S (and others who may not have understood) - A famous carnatic singer sings a pure classical song when the lady (actress by name of Suhasini) - dares to ask him something on the lines of why he cannot introduce popular songs interspersed with classical songs too - and also why not explain the classical songs. This argument ends up in the singer asking Suhasini to demo by singing - which she does - and therein validates all points in her argument that "regular" songs also have a raaga, thalam etc.)
