Hm. The "talkin' 2 myself" era was rough and unsual edgy for a pop singer. I think it was a terrific time in terms of vocals and appearance. Far from being a disaster. On the other hand, these opinions acknowledge my assumption that it was rough and unusal, indeed
Truth be told, I always prefer the pre-GUILTY vocals. A Song for XX to Secret, to be exact. For some reason, GUILTY takes a special place in it though, because it's the only album to this day, that I would not have liked to have these notorious, bright and high-pitched vocals of Ayu. "glitter" functions as a short break for taking a deep breath before the depressive mood continues with "MY ALL". I always found that so funny.
