I have just got a great idea.
Not yor Ayu, but I will train my Ayu rock songs (from Secret) karaoke. Then I will show my friends, Ayu have done a great album, so they will be buy it lol
Seriously, I think it will be very hard to boost sales, I don't really care about sales but I wonder what Ayu thinks about it, will she get depressed for it and makes no more good songs? Or will she try to create original songs?
I think Ayu don't really care and will continue to sing until she is fed up singing
But who knows what Ayu really thinks.
