Not only previews, but the PV for Shiroi Kisetsu is also available on Youtube! Also, the single has leaked, and it's a solid one. I've been listening to it for the whole evening and haven't really gotten bored with it. All the songs are nice, none of them neither amazing nor dull -- Sakura Hitohira and Cande of Life (and its remix) are the best of the bunch for me.
I'm happy she put out such a meaty single and still made it really good.
Also, how come I never knew there was a MISIA thread here?! This would've come in useful back when I was discovering her and having my mind blown by DEEPNESS.
