"sixxxxxx" is an absolute masterpiece!
Not only did I already love the first three songs, we've heard, already...but the last three songs just top it all off.
Truly amazing! I love how "Sorrows" is all rock/love..."Shape of love" actually reminds me a bit of "BALLAD" (which I love!
) so of course I'm in total love with it...and I just can't get over how beautiful/fresh the melody of "Sky high" is.
Overall, this is probably my most favorite mini album from ayu & come to think of it...dare I say that I actually think this mini album blows the entire "A ONE" album...out the water?!
(I still love "A ONE", though...) 
Amaaazing job with "sixxxxxx", ayu!
