This movie was on late 90’s, early 2000’s. It was in English, color, and I saw it on tv. Opening scene: a kid is studying when he puts on headphones and listens to music. His mother walks up and strangles him to death. Next, a guy, dark long hair breaks down in a town where no music is allowed. While waiting in town he learns the reason is the townspeople believe that music will summon a ghost. At the end the man convinces everyone its just superstition and they all sing amazing grace until the ghost actually appears and attacks and it cuts to black.
