Taike makes great sense with this statement...

"You should also keep in mind that since home players are the main buyers of the Tyros 3, it makes sense for Miss Nakagawa to play songs that are approachable to such players. The potential buyer should be left with the feeling that they can produce the same stuff. Over-the-top playing will only scare them off.

I know using the same technique works very successfully for me in my demos.
