A plain audio file metadata extractor ("scanner") especially for classical music. It basically creates an SQLite database to be used by player applications like the Unpoular Music Player or the Opus 1 Music Player. As "pop music" is an abbreviation for "popular music", any other music obviously is "unpopular", so this program could also be called Unpopular Music Scanner.
