First remix album is really good. I totally love that 8 minutes long No Regret remix the most, also WIND -PORTABLE REMIX- (If you didn't know, she sang this remix on her Kingdom Tour x) is really good.
And about Kuu intros. I gotta agree. Those are ****in' epic lol. I'm always really addicted to those since they are always so good. Black Cherry's intro killed my soul. Literally. It was so good I got shivers going down my spine when I first heard it. Before that I had listened to BEST ~second session~ and I was so happy I had listened to the album. When I heard INTRODUCTION, I was like "WOW".
I don't understand what is it but somehow Kuu intros are always the best among others I've heard. Oh well, it's Kuu.
