Ada... A Way of Life (transl. Testimony) is a 2010 Hindi musical film written and directed by Tanvir Ahmad, with music by A. R. Rahman. Rahman composed the songs for Ada in 2001, after completing the score for Lagaan, but Ahmad's plans for the film were shelved. Though the music was composed for the original concept, the film features a new script as well as different actors, as it stars debuting actor Ayaan Ahmed, the director's son. Along with its notable composer, the soundtrack also features award-winning singer Jayachandran, contributing vocals for the first time to a Hindi language film.
