I can state my opinion, just that this really doesn't have to do with opinion. If Ayu sold 50 million copies of her new album and someone called that bad, would it be right because it's an opinion? If you say yes you're a liar, if you say no a hypocrite.
Also, you never stated your posts as an opinion before this last one. The only way to compare sales in a declining economy is by looking at other artists and unless everything below the top5 is bad, Ayu sells very well. Ayu is perfectly in the overall drop of sales, basically EXACTLY there and has been for some time. If you calculate with that you will notice that in fact, Ayu is not selling worse, she is selling less, but not worse than in the last years. She is, however, selling worse than around her peak, but no peak has ever lasted more than a few years for any artist.

Her tours(which obviously make her main income) have just been becoming bigger and tickets selling better over the past years and for her PVs I'm pretty sure she pays at least part herself, ever since she started doing million-dollar PVs their singles/albums either hardly got the money back in or not at all, there is no way avex is paying for that.
