Jagadhananda karaka (Sri Rama rajyam) and sudhadhanyasi

Jagadhananda karaka from Sri Rama rajyam is in the sudhadhanyasi scale......but look at the majestic way it is used here and also the romantic way in sempoovae poovae, and contrast it with the innocent folking way it is used in kudhikira kudhikara (azhagar saamiyin kudhirai)...Then the devotional way thalaivar used it in the starting few lines of "pooeru konum" from thiruvasagam?

below are sudhadhanyasi gems from Raaja -- check out the various styles of using the scale.
