We expect the manufacturer to listen to the customers but deny him to take part in the discussions on this forum. I find this very odd.

To me it's not the styles but the arrangement that makes the difference. Anyone can play a song but not everyone can make it sound good. A good style doesn't make a bad player sound any better.
