Good job! Now those files are recognized without problems...
... and I unearthed another bug

. Seems something is wrong with the recursive search, because although it works in my main music directory, counting every file located in the nested directories, when I input the main directory (My Documents) containing the two separate music directories that I have, only one is searched! The other one does not show its results in the graph.
EDIT: And another one, this time a exception. I have various pictures for each album I have together with the music files, and it seems the program doesn't like cover pictures, at least one of them, because it throws a "External Exception EEFFACE" when it gets to this picture, and it seems the scanning routine gets stopped there, as the status bar shows it's analyzing this file. I wonder if this could be caused by the fact that this picture is duplicated in two different directories. The exception only occurs when I select "Genre" in "Display chart by". And pushing "Stop" button does nothing.
