Yes..., it DOES fall into another category. One category it DOES NOT fall into is for the "Western Market". I don't see anything wrong with this demo as he's providing it for another market. You may not like the version of the styles he's playing, but the different genres don't sound the same around the world.

This video isn't even in "english". Clearly he's capable of putting out good demos that appeal to the western market. His PSR-2000, 3000, S-900, and Tyros 2 demos show this.

I think you're being a little too hard on this one. If this was a video in english for the western market with the same music playing.., then I'd say "fire away" as these do not reflect the western versions.
