Career low point?

Well, it seems that a lot of people have said at different points in Ayu's career, that it was at a low point.

I don't really think she has had one since her release of A Song for XX, but I like reading people's opinions.

So do you think Ayu has ever had a "low point" in her career? Like, some people say NEXT LEVEL is or RnRC is... etc. It can be in terms of songs, photoshoots, PVs, image, anything. And if you don't think so, state that too.

And if there is a thread like this already, I'm sorry. <3
