I see ...
Checked the list of Raags of IR songs posted by Karthickcb and was amazed to find these songs under the Raga Chakravagam - they all sound entire different :

- Appa Kada Anna Kili (Payul Puli)
- Marandhen Pirandhen (Gitanjali Devotional)
- Vanithamani Vanamogini (Vikaram)

To an amature like myself, these 3 songs don't have the same sound. Amazing.
But I find that this Raga was used by IR for duets alone in Film Music and Mohanam is mixed, the female solo taking the centre stage.

- Abc Nee Vaasi (Kaidhiyin Dairy) is a jolly song, now I find it more jolly.
- Poovil Vandu (Kadhal Oviyam) super Pattu
- Oru Ragam Padalodu (Anandha Ragam) Yesudas humming just ignites means. Did you mean the pathos version of this song or is there another ?

By the by, all my favorite songs are under Mohanam Raga, thus making it my favorite Raga ... LoL
