Ayu is really making a comeback with this release; the songs are really impressive. I think the weakest of the 3 tracks is "Melody," but I think that's just because some parts of the song remind me of "TO BE" too much. Anyone else feel that way? Even then, the song's chorus does make it distinct from her older songs, and I like the song overall.
"Song 4 u" is absolutely amazing. Same goes for "Missing." I really hope "again" is just as good, if not better, than this release.
