[mizuki-7]

Honestly nothing has been done to moves some sales ... The popularity of Ayu is what she is but it sound to me like besides her fans and some people following musical accounts on social media nobody are aware that she released a new album and it’s like that since some times now...
No tie in, no promo, no interviews, underwhelming contents etc... even with that i cant assure that her sales would be much better but it would definitly grabe some interest from nostalgic people of her songs.

The singers of her generation who are doing better than her at the moment have all big tie in and promo. These singers probably have a better likeability than Ayu but still ...
