It seems to me that AVEX sort of rushed the 50th single anyway. With the right hype and the right promotion, Moon/Blossom, Crossroad and the 50th single could've reached atleast 100k the first week, cause this is a big milestone.
But it seems that AVEX isn't interested in high sales or anything, but more to just rush out her 50th song instead of making it memorable. You don't just reach the 50th single everyday.
Oh well.
