I didn't really like the single either, and I bought it XD
Well Mamotte Agetai is quite nice, just nothing mind blowing like she used to do some time ago. I even liked Let it go better as a single.
Kiss me isn't really appealing and Yuna's voice sounds annoying sometimes
I liked the first part of the remix, but then it just kept on going and going nowhere...
Still nice to have some new material from Yuna
