^With me, it's less about personality than an approach to music. You have been given a gift, a talent, then frigging celebrate it! Stop being so damned angsty about it! Be a little more grateful. And, personally, it comes across in their music and performances. There is a noticeable lack of passion.
That's why I respect artists who work hard and find joy in sharing their gifts and talents with others moreso than those who tend to be "cold" towards their own abilities and what they can give to the world.

But I was talking more about the artistry B'z has compared to the general lack of any in visual kei.
