I'm in two minds about this.
Firstly - what has irked me is the tracklist. 7 songs? 1 song ("One Dream") was released months ago too.

This is so unlike SM. And adding the two instrumentals on the end is SOOOO Un-SM, they never do that! So I'm a bit pissed about that.
Despite the shortness of the album, I actually think the first six tracks are fantastic. I was in a complete state of shock when I first heard the album - it was absolutely nothing what I expected. It is absolutely nothing like "Hurricane Venus" and that totally shocked me - so I was definately dumbfounded on the first listen. But the more I listened to it, the more I realised it's such an amazing album, alebit too short. It definately reminded me of her Japanese material - which makes me think that these songs will come out in Japan very soon.
Aside from the complete 180 in the style of the music and the shortness, I think it's a fantastic album.
"The Shadow" is by far my favourite - Perfect song.
