Hi Guys The songs in which I could find the similarity are Sonnalum from Kadhal Virus by ARR and Uyire En Uyire by Harris Jayaraj from Totti Jaya (I donno if dis song is used in the film as or not as I've not seen it but its there in the album). I think both the sngs r based on the same raaga eventhough I donno anything abt raagas. But the truth is Uyire En Uyire sung by Karthik Anuradha Sriram & Bombay Jayashree is simply awesome (Needless to say abt Sonnalum as everyone knows abt the song).
Ur views... Anand
