If you watch the documentary of the ASIA tour 2007 where Ayu suddenly breaks into tears in the beginning of Surreal, you'll notice that her voice is much smoother than the concert that was taped for the DVD. In the concert of the DVD she has a much more deeper voice, and maybe that's what happens in the course of a our. In the beginning of the tour her voice is as much as ''unused'', and at the end it's more lika ''overused'' ans causes her voice to change. I guess that's why we can't really expect her voice to be as good and smooth as at the beginning of this tour. And we must include the facts that she had more than 30 dates this year, plus that she lost her voice earlier this year
