1. Ayu's image changed from creative to recycling (I don't mean tour costumes), sometimes I think ppl look at her more and more pitifully.
2. Too much unnecessary stuff (when your favourite artist produces too much you start being selctive, by being selective sales drop and other ppl buy less too, instead of concentrating on new things she releases too much BEST of)
3. Too much illegal downloads, but in fact all the artists have lower sales than before.
If I have to chose between buying Ayu concert which can be easily found in the net and Kinki Kids concert which is almost impossible to download, I chose KK, unfortunately, and I'm not proud of it. Japanese concerts cost 1/3 - 1/4 of my month salary, it's impossible to support artists each time they release sth
I wish I could buy Ayu stuff the moment they are released, I only bought My Story Tour this way and it cost me 6,050 yen + tax (my salary at that time was 25.000yen / month), all the rest I have from Book Off, so second hand.
