Sometime between the years 2007 and 2011 I watched an awesome horror movie late at night on cable tv. I can't remember what channel it was on but I'm sure the name was something like "The Devil's Sonata." After years of searching the internet I have made 0% progress. If this movie sounds at all familiar, can you please pass on any details? I would love to watch it again. A more detailed plot summary is below.
