Update : After a long hiatus (standard reasons may apply), I've started work on that list again and here's how far I've come -- yes, I've actually forced myself to listen to every item in that list...

There are some points that stump me however such as :
a) The difference between a keertanam and a kriti -- where do you draw that line? Not to mention things like devarnamas or sankeertanams that have been tuned to CM. I'm not sure at times what to call them. That part can therefore get a bit arbitrary at times.
b) I made a big mistake in the beginning not using the Harvard Kyoto convention for the syllables. So about half the list needs to be fully re-edited to fix that...

. Nevertheless I still don't use it exactly. I prefer not to use "I" where "ee" could be clearer since it looks identical to a small "l" most of the time. And I don't like to use a "c" for cha. I prefer "ch" for the normal syllable and "CH" for the aspirated version. Barring that deviation, everything is as per that convention now.
c) There is a separate list for varnams, inspired after mass looting on sangeethapriya yielded a much bigger pot than I ever imagined

. However, it has also kind of made me aware of my vast ignorance in this area. I believe I've undone my own wicket when it comes to classifying varnams into various types... and finally I've given up. I believe that part of the list is all wrong.
d) I found that going by composer is the best way to list and exhaust a set of compositions (with the exception of varnams) -- I'd even suggest that apart from listening by artist or raga, to REALLY broaden your repertoire you must listen by composer. Right now I am (still) on Thyagaraja for the last 4 (FOUR!) months... am itching to get to Dikshitar and OVK.
e) At times I have mistaken a 1 kalai for a 2 kalai and vice versa... in fact not having videos or having seen the renditions live means there may be quite a few mistaken cases like that.
f) I realized there was a thing called viloma chApu...
g) Many songs classified as "tripuTa" or "jhampa" are really in mishra chApu and khanDa chApu respectively.
h) Reports of Ariyakudi's repertoire in Thodi are not exaggerated.
i) My Brinda Mukta collections have gone up to an all time high -- I never knew there were that many recordings out there.
j) There are some compositions in the sangeethapriya tribute pages that have the wrong recording for it.
I'll need expert help in the future as I believe that despite all the progress, there'll be tons of bugs to exterminate....
The experience has pushed me totally into unknown territory to the point where unknown has become the new normal. But the rewards are worth more than I fathomed.
A great many thanks to karnatik.com, sahityam.net as well as @lakshman and @vgovindan for their incredible efforts.
