The hand thing is one of my ultimate pet peeves.
But not with Ayu though because she is on the low end of offenders when it comes to that.
As for the You Were and Rule performances being "good." Are they considered good because she sounds similar to how the recording does? Because imo, that just means that her studio vocals have problems too. Both songs are very shouty and choppy sounding in their studio versions and they sound that way live too. I love the melody and music of both songs but her vocals are the weak point of the those tracks for me.
