I'm in love with Miracle Worker, it's a perfect pop piece for 2016 Perfume, and sooo addictive.

The album as a whole is kind of a step down from LEVEL3 though. None of the other new songs quite reach Miracle Worker, STAR TRAIN, and Pick Me Up's level of quality (Cosmic Explorer certainly tries, and it's a good song, but I just don't think that a sound this heavy suits Perfume very well; Next Stage with YOU sounds nice, but with how little melody there is, it also feels like Nakata just got bored with it halfway through; FLASH is just really boring melodically, but at least the album mix sounds more interesting; STORY is clearly made for the visuals; Baby Face is nice if a bit unmemorable), and many of the singles for this album weren't that great (I still fail to see any appeal in TOKIMEKI LIGHTS or Cling Cling, but at least the latter also got a spiced-up album mix), but on the bright side, I've started liking Relax In The City and Hold Your Hand more as parts of this album. I just wish Nakata found some new inspiration because I'm not loving his EDM-influenced work.
But hey, I'm happy the album sold well!
