She did well on MSta, that little mistake in the beginning did make me grin a bit haha.
I'm really excited for the new ballad, and the preview just screams hit. It definitely feels more like Yume no Uta or Ai no Uta, than Ai wo Tomenaide, which was the last ballad single. I am curious about how she is going to promote it, though. With her touring and taking care of a child, I could see her only doing MSta, CDTV, and then using the year-end shows to keep to promo going. I also think that the tie-in(s) will most likely be CM tie-ins, since most of the drama tie-ins have already been announced.
I definitely think that if she can hold above 5k to 6k in sales today, then a 55k to 60k debut could happen with a minor adjustment.
