The four a-sides are available at jpopsuki. I have just istened to them, and had a big dissapointment (I expected it to be a lot better). Here I go with my mini-review...
The songs aren't anywhere near the goodness of the 12 previous singles and Koi no Tsubomi. Only one arrangement is good and looks to have been worked out hard: With your smile, the dance a-side. It's a very good song, and the only one I'd save out of the four. Maybe I'd save JUICY too. It's like a typical R&B Kumi song, but a little US-ish. You'll notice what I mean when you'll listen to it. Ningyohime looks like one of those Ayu werid rock songs that are worth nothing. It seems that AVEX can't pull out decent rock music on their pop artists. And finally, there is I'll be there. The song is good, but it is very generic, very very generic. It's mid-tempo summer-ish poprock. Good to be on an album, but not enough to be an a-side, I think.
