I of late see quite many raagas entering film music again. I hardly listen. but the one that recently noticed were
the one from subramanium in raaga ritigowla? i dont know the song. I think it is kangal irundhaal kangal irundhal.
there was one other reethigowla sometimes back
Sudum nilavu sudaatha sooriyan from thambi.
then the abhogi from chandramukhi that all know
Konjaneram konjaneram konji pesa koodaatha
do you come accross such things often rasikas. some other latest or recent ones with classical raaga flovor???
