It's fairly good, but I'm not sure her vocals are commanding and compelling enough to demand my attention.
What are the chances she actually achieves any substantial solo success?
Well, simple answer probably not much.
Her success is mainly her Dear J debut and anything associated to her image as an AKB48 diva.
AKB48 isn't a gateway into the mainstream. It's more like a school for girls interested in entertainment...even though may not completely transformed into their whatever goal they had..it's like hey..."why not test the waters to see how far you reach before you actually fly right in?" Kind of like American Idol but releasing music before the finale. Girls graduate from idol groups don't fair to well but hey. If they weren't discovered to be a sensations already, chances are they wont become one.
My thoughts on Itano is that she'll probably fizzle out and become more of a fashion icon and marry up with someone.
Atsuko still has some appropriate success alone, so who knows...the next Aya Ueto?
