I want to say that the soundtrack has some stuff from Neu! (the song you are referencing), Tangerine Dream, and Kraftwerk...all unlicensed of course.
Is the Japanese character the same guy who plays Evil Betty in Kung Pow: Enter the Fist? I think he is. I also think the guy who play Wimp Low is in this movie as well.
Ah, good times, good times.
I would guess so. It's worth noting that the film Kung Pow is based on stars Jimmy Wang Yu (star and director of MOTFG), they show a brief clip of him in the end credits.
