I found this comment by K.S. Ravikumar quite interesting that ARR is not keen to compose romantic songs (duets). as far as I see it is not that true but at the same time not too wrong either. the number of romantic duets songs is decreasing in his albums lately. recent examples are Delhi 6, Blue, Ghajini where there is barely one romantic duet or not at all. - Jahanzeb
