There are longer previews of all the tracks :

(But with single versions of Feel the love/Merry Go round.)
EDIT :
XOXO : I don't really like this kind of electro :/ and her english is bad, very bad XDD
What is forever love : definitely Urata Naoya.... Meh
Terminal : more dance-y than I thought
NOW & 4EVA : classic Pop/Rock Ayu track, I'm really satisfied with it

Reminds me of Tell All
Lelio : more english... Don't really like her voice here, but the beat is good ^^
Angel : Don't get the hate for this song... the low pace really is good to me, it's a beatiful song I think
Globally, I didn't expect SO MUCH electro in this album, we certainly aren't gonna need any remix album for it hahaha. I feel a little sad that Ayu's music isn't "unique" anymore, but resembles to any today's song we can hear on radio

Not that I don't like electro (i like dropping the bass sometimes lol), but before that, listening to Ayu allowed me to "escape" from today's (crappy) radio's trends. If she's gonna release more and more songs like that, ther's no point (to me) to listen to Ayu :/
(IT'S MY OPINION)
