You've probably already bought the album by now, but I'll comment anyway :P I'd give it a 5 :D It's definitely my favourite album by Kuu, pretty much all the songs are solid, a few are really awesome and I'm glad there's not tonnes of ballads everywhere. The only songs I'm not hot on are:
Brave - just feels really generic and a snoozefest for me.
Everyday - yuck! I only really listen to this if it comes up on shuffle
All for you - this has really grown on me, but originally the pretty much non-existant production was weird for my ears.

The rest of the album is :heart for me though. The packaging and image is beautiful too.

Unfortunately I gotta give this album a 3/5. I keep telling myself that it's amazing and one of her best albums but the only person I'm fooling is myself. These are the songs I didn't delete off my computer:

So Nice, ESCALATE, V.I.P., Boom Boom Boys, Lay Down, Slow, Everyday, IN THE AIR, and No Man's Land.

It seems like a lot until you realize the album has 19 tracks and I only listed 9. That's less than half.

Also I like Everyday but damn it sounds like such a Kingdom song. It really really really reminds me of a mixture of himitsu and koi no mahou. It should have been on Kingdom.
