This topic is rather difficult. We are not discussiong prosody in general in literary poems in any language like Thamizh or other languages based on Sanskrit . We should select only such lyrics which are either
set to tune by the original lyrics-composers or retuned by others. As such , prosody does not deal with theme at all, philosophical or other
such. Such thematic excellence and literary graces in metaphors and like are bonus. (This is a point, consistently held by
@shankarank .....if I follow him correctly...he would even assert that prosody itself is /music/ ? ---untenable though it is.
as that would lead to mixing up literature with music , Music need not always have lyrics, Where is prosody and philosophy in an instrumental rendition..?

Nonetheless, CM always gives equal importance to lyrics and that is where prosody comes in CM.
.Thamizh poetry excels in natural rhyming. Barathy though not trained in CM, had a natural music sensitivity and seems to have sung many of his poetic creations , already set to a raaga of his choice. though, not all the compositions have been rendered in the melody suggested by him , by musicians .
So, discussing prosody in CM, should be strictly confined to the musical compositions in CM from Daasa saahithyams...onwards.

Re-tuned songs can be considered here as we are dealing with prosody / set to music/. and in circulation. Almost all the Barathy poems set to music by others, are very rich in the typical and unique prosody, which we do not find in any other language so overwhelmingly.

/ பொழுது /புலர்ந்தது; யாம்செய்த தவத்தால்,
புன்மை யிருட்கணம் போயின யாவும்;
/எழுபசும்/ பொற்சுடர் எங்கணும் பரவி
/எழுந்து /விளங்கியது அறிவெனும் இரவி;
/தொழுதுனை /வாழ்த்தி வணங்குதற்கு இங்குஉன்
தொண்டர்பல் லாயிரர் சூழ்ந்துநிற் கின்றோம்;
/விழிதுயில்/ கின்றனை இன்னும்எம் தாயே!
வியப்பிது காண்!பள்ளி யெழுந்தரு ளாயே!
