I think Ayu should re-release A Song for XX this year or next. Or at least re-arrange/release poker face, because it's her first single. I'd really like to hear that as a remade version. I'm sure it will sound awesome. <3
And about what she should do to sell better; release albums as CD Only, CD+DVD and CD+2DVD like Koda Kumi, or make some new themes for TV dramas like Hikki did with her Flavor of Life song. :3 I would like these both ideas a lot, it would work fine.
But I don't really care about the sales or position or her fame, because I'm sure people does respect Ayu even if her sales are less than 100,000 per album nowadays. I think, for her, selling over 500,000 is awesome thing. :> She's not selling as bad as I thought she would be. But she's still Ayu, even she doesn't sell over a million per album like in 1999-2004 she did. ^^
