Where is the music director?

I have been noticing a disturbing trend off late in music release functions---in most cases the music director is sidelined or not there! It is a MUSIC RELEASE function and the focus is always on the actors or the guests and never on the person responsible for the event, the music director (along with the producer/director of course!). It is very irritating to see even articles sometimes covering music launches but there is no mention of who the music composer of the movie is. The problem I believe is that today producers/directors believe that music is just an add-on for the movie and not an integral part of it.
Only directors like Maniratnam, Shankar, Karu Palaniappan, Gautam Menon, Aditya Chopra etc. have been promoting the music with some keen interest and passion. Most others consider it as just another part of a movie, when actually it is not. If the music of a movie is done well with care then everybody would realize that it acts as the best promotional tool for any movie and the songs are on everybody's lips before the movie releases! Case in point is Vaaranam Aayiram. This will do wonders to the movie's publicity. This is the reason we find generally the songs in the movies of the above mentioned directors to be excellent and they add to the overall beauty of the movie. I just pray that this disturbing trend ends soon and music directors get their due.
