Yes I guess you are right. The trend today is to have a few fights and a few dances; stories play a minimal role in movie making.
For the last few years hooliganism and gangsterism were the key factors in most movies (including maniratnam's!)
Now the trend is to make movies of psychopaths.
Songs have become merely the advertisement tool for movies, rather than being part of the core.
What use have songs for the old men/women in such movies.
