I think only nee paartha was peerless. raam raam was actually quite popular, ofcourse because of the type of music. I liked the isaiyil song but read a review which said "dull orchestration lets the song down, so the singer is left to improve the song" And a popular song need not be fast and peppy. take lagaan or azhagi for instance. folk melodies will also work! talking of lagaan I was watching the film with few of my friends recently and they were appreciating ARRs Bgm in each and every scene. They are not ARR fans but casual listeners, but his BGMs presence was more visible. ARR really does well when it comes to grandeur and pace. IRs forte is emotions.
