I've always been quite a big fan of Ayaya, her first single "Dokkidoki! LOVE Mail" was a hit and for good reason. I still find it a really catchy and cute song~
Aya's really evolved greatly since that time, a lot of us have seen her grown from that cute, pint-sized 14 year old to a great woman of today. I guess, one of my most favorite songs from her would be "YOUR SONG ~Seishun Sensei~", but I love a lot of her songs really.
a lot of people have wondered what she's up to now, for those who don't know, she's mostly been doing commercials and promoting a host of other things. I really wish she'd release a more upbeat single soon, she's released 4 ballads in a row. I miss seeing something like "Kiseki no Kaori Dance" or "The Bigaku" from her...she's still young and would still be OK for her to do slightly cutesy upbeat songs.
she should do as much as she can before she hits around Yuko's age (late 20's up to 30+), where doing cutesy songs isn't seen as "right" in a sense for an idol anymore.
but, she did mention she wants to get married in her early 20's like her mother so who knows? she might leave H!P to get married within a few years.
