Why our filmmakers are particular about titles?

Why are filmmakers and actors more concerned about film titles nowadays. Most of them want catchy titles that can ring a bell and probably have big recall value in the minds of the audience. While filmmakers seem to be running out of catchy titles, and therefore, are opting to have the first line of a hit chartbuster of their film title.
Filmmakers are fighting to have a very catchy title and in most cases, it’s the fans of the actors who end up fighting. Titles have become the biggest concern for directors, actors and producers more than even the story of a film. More and more actors prefer picking titles that are already popular in the industry. For instance, Sudheer Babu’s next film is titled Aadu Magadra Bujji, which is a famous line from Athadu.
The Manchu family has opted for Paandavulu Paandavulu Thummeda as the title for its family multi-starrer, while Sai Dharam Tej’s new film Pilla Nuvvu Leni Jeevitham, is named after the opening line of popular song from Gabbar Singh.
