The story
Originally "filk music" was a typo for "folk music" in a never-published essay on the influence of Science Fiction and Fantasy on folk music. Its first known deliberate use was by Karen Kruse Anderson in Die Zeitschrift für Vollständigen Unsinn (The Journal for Utter Nonsense) #774 (June 1953), for a song written by science-fiction author Poul Anderson.
Today it means
adj About or inspired by science fiction, fantasy, horror, science, and/or subjects of interest to fans of speculative fiction; frequently, being a song whose lyrics have been altered to refer to science fiction; parodying. (However, much filk music is original rather than parodic.)
Language periods are conventional ranges, not dates for this word.
