1. Yes, I love the 'fake Japanese' style! It looked really cool for the covers.

Nanami - It's actually Ayumi who started calling it "fake Japanese"

2. Ayumi's voice is better now only because she's learned to control her voice and she doesn't sing from her throat anymore. I also think she's a smoker, so her voice has a deeper quality now.

re: vibrato. Ayumi's vibrato isn't a natural vibrato, she uses her lips to make the "wavy" sound. I find it annoying, actually, and wish she wouldn't overdo it like she does live.
