1. Mahaveera Vaibhavam (a.k.a Raghuveera Gadyam): The very very unique and rapid style in which this prose is recited makes this one of the best Sthothras composed by Desikan. It takes several years for people to learn to recite this correctly. The entire sthothra is culled form different parts of Valmiki Ramayanam and is simply an abridged version of the entire Ramyanam. For once a composer puts the focus on the 'warrior' aspect of Rama. Listen here and read along here and here.
2. MannuPugazh Kosalai (Thaalattu or Lullaby for Rama): A fantastic carnatic style rendition of this prabhandham. A fantastic song for babies to listen as they go to sleep. This is recited sandhai style in a very fascinating way too. Refers to SenPonSei Kovil.
3. Bhadrachala Ramadass by M. Balamurali Krishna: One of the best singers ever at his best.
