I see nothing bad about lipsynching for certain songs, it´s normal for stars like Ayu, Kumi or also Western stars like Britney Spears to lipsynch upbeat songs with a lot of dancing/moving. And Ayu´s cute sections are a lot of moving, and it is really hard to dance + sing at the same time, esspecially such high note songs like posker face or honey. So just try it before you blame the artist for that.
And you never should forget that Ayu is not a singer when she is on Tour, she is a performer.
