I don't like Thank U with all its lalala's, but I love the other album tracks
like a doll + do it again are my favorites, but November and sending mail are really good as well <3
I'm happy I like them, because I wasn't expecting much at first XD
The tracks are a bit repetitive but I think it's not that bad if you actually know Japanese (or at least read a translation).
And, the lyrics are beautiful <3
November's arrangement reminds me of a Final Fantasy tune though XD I just can't remember which
And insomnia's first 15 seconds instantly reminded me of tune played in FFX-2 when you meet Shuyin in that cave (I'm not saying it's ripped off or anything, it's just interesting to me)
