I feel Anirudh music has IRs tunes.. his violin and flute and the melody bit in songs and background.. cant avoid the feel of hearing it somewhere..and IR naturally comes.. i am not great person in music.. i cant note particular songs or BGM of IRs with Aniruth.. but sure he brings in IRs touch...in almost 75% of his songs and BGM. which surprisingly i cant see with Yuvan. not sure where i am the only person who get that feeling !!
