Yeah when I didnt see a thread for Ayaya I was like 0.o...
So I started to talking momusufan on MSN about making one 
All thsoe pics of Ayaya are so cute, Ayaya is one of the most beautiful women I have ever seen!
OH and Kuriyama, dont you like Suna Wo Kamu Youni....... NAMIDA and Rainbow 7? I think they are great!
Let me revert back to my old avatar to answer this:
First off, I like just about anything Matsuura touches, so yeah, I like the song. She's obviously H!P's biggest vocal talent and in the top 3 for all-media talents (with Yaguchi and Gotou).
In response to what Sev said, the thing about Aya is you can tell she really doesn't give a f*ck about anybody else in H!P except for maybe Miki; hell I dont think she even cares all that much about what she does, she just does it cuz she can and she's good at it, IMO.
About my opinion of Rainbow 7, you can read my responses in its respective thread to answer this. But in short: it sucks, I can hardly listen to one song all the way through. Let's be honest, the singing, by any standard, is 73.1% horrendously intolerable, especially on the slow songs (unless Tsunku is filling in the harmony).
That's why I said 'sunawokamuyouni...namida' which literally means "like chewing sand...tears", is about listening to Rainbow 7, because that's exactly what it feels like. You wanna like the album, but you gotta grind your teeth to listen to it, you can hardly wait for each song to finish. !(Blind optimsm will hurt you in the end)!
And if you were wondering what this...

..was about, it was alluding to the possibility that this could and probably should be Morning :c16: Musume's last album.
I mean come on, the vocal and production quality have significantly dropped, and after Yossie and Mikitty's departure there will be no adequate leadership.
(DO NOT try to argue for Takahashi, or you will be immediately debunked and branded a fool.)
