Sucess for bollywood

Bollywood films are generally musicals, and are expected to contain catchy music in the form of song-and-dance numbers woven into the script. A film's success often depends on the quality of such musical numbers.Indeed, a film's music is often released before the movie itself and helps increase the audience.

Indian audiences expect full value for their money, with a good entertainer generally referred to as paisa vasool, (literally, "money's worth"). Songs and dances, love triangles, comedy and dare-devil thrills — all are mixed up in a three-hour-long extravaganza with an intermission. Such movies are called masala films, after the Hindustani word for a spice mixture, masala. Like masalas, these movies are a mixture of many things.
