Hey Valde,
Have you by any chance learned the background of the word "satire" from the introduction to the book "The Invaders Plan" by L Ron Hubbard?
Its the first book in his Mission Earth series.
I just read the intro a couple of days ago and learned the same lesson it seems.
In any case, its an interesting connection you are making.
I would agree with YouRTheMachine though.
I don't think Champloo satirizes the culture or the hisory at all.
A playful look/interpretation maybe.
It sure is a nice medley though, and I belive its good for you.
So keep on enjoying!
