following is the list of my all time favourites which i felt should definitely be mentioned over here
1)one of my personal favourites in the melody section is the song"yamunai aatrile" from thalapathy. what a woman! shobhana looks absolutely gorgeous and the song is so so nice. i like the lighting also in that song.the sunset fits in perfectly
2)netru illatha madham from pudhu mugam reason: the high pitch and the lyrics esp lines like" gangai neerun suvai kadhalum serum varai kavidhai variyun suvai artham puriyum varai " these might look simple yet make sense.
3) another song from the same movie is kannuku mai azhagu. i prefer the male version better .
4) pogathe song from deepavali under yuvan's composition
5) athangara maname song though am still not sure which movie this one was featured in but i seriously like mano's energy in this duet.
6) if english was considered then the " its only words" by the now nonexistent boyzone can be included.
7)pudhu velai mazhai from roja. i like the picturisation too :P
the list goes on but these are the few which came to my mind now .feel free to add more :D
