"filk" is best described as the music of science fiction fandom, or at least, the music of the filk community. Songs about SF books or movies, fandom in-jokes, or even just related topics such as computer geeky references are all common sources for filk. And, despite what the self-demonstration says, filk doesn't have to be new words to old music, or spoofs of the lyrics of original songs — many filk songs are originals. Filk can also be thought of a special genre of Folk Music.
