Imagine if people were saying Mariah Carey, Christina Aguilera, Britney Spears, Rihanna and most pop girls are retiring for not releasing new music every year (they usually take 3 to 6 years between releases) so I don't see why start talking about retiring in Ayu's case. Even if we don't count TROUBLE (I do but some people act like it doesn't exist) MIJ was realeased just about 3 years ago, is not really a long period (compared to others artists) and during those years she toured like crazy, like it or not, as long as she keeps touring she's active and even if she decided to stop realising new music she still has a HUGE catalog of songs to do another 20 different tours
