Swamy, it is not clear what you mean by “a to z sorted”.

I presume, you mean all ~4000 songs recitation arranged by their traditional classification.

For beginners like us who are entangled in so many diverse daily activities with very little dedicated time for learning the prabhandam, downloading all ~4000 at one go will be overwhelming. We will end up not learning even a little bit properly. Moreover, it is not really essential to rote learn all of them just to feel good. Even just one set of songs (eg. Thiruppavai) learnt well and recited on a regular basis with ever deepening devotion is much better than learning all ~4000 but not reciting them regularly.

We can start with the nithyanusandanam songs (Thiruppallaandu, Thiruppalli ezhuchchi, Thiruppaavai, Amalanaadhipiran, Kanninun-siruthaambu); learn and recite them daily / atleast frequently, with ever increasing absorption in the deep meanings of these songs.

These sets of songs can be learnt through proper sandhai training here: (https://www.kinchit.org/audio/) Kinchitkaram Trust » Audio

Once these are learnt, you may consider Ramanuja-nootrandhadhi.
