What is a FILK? EOM

[Kenneth M. Kuller <ken.kuller@veritas.com>]

I'm not an expert, but I think the answer is anything that is 
sung "to the tune of...."  

A longer answer is that filk appears to be a collection of parodies 
and other music, set to existing tunes. The bulk of this 
broad "other" category tends to be dominated by songs about 
characters and situations from science fiction or fantasy literature.

For example, 
  Quidditch Fan Song 
  (To the tune of Take Me Out to the Ball Game) 

  Take me out to see Quidditch
  Take me out for the match
  Buy me Bertie's Every Flavor Beans
  I love them all except if they're green
  And we'll root root root for the Seeker
  Let's hope that he grabs the Snitch
  For it's one-hundred fifty points when you play Quidditch!
