The soundtrack is masterful. The songs, instrumental versions and themes that together are the soundtrack for "Bose - The Forgotten Hero" are all wonderfully composed. A R Rahman has infused traditional songs such as "Ekla Chalo Re" and "Kadam Kadam Badhaaye Jaa" with emotion and energy, and also created some good songs on his own, the most impressive being "Zikr" - the continual chanting of Allah's name. The themes that form the background score seem to be composed to go with the situations and locations of the various scenes in the movie.
A must-buy soundtrack.
Now waiting for the movie.
