i think with only one edition (& it's limited, right?) the new single won't produce the amount of a second week as "Monster," imho. i think Ayu is safe for the most part (unless JE drops a KinKi Kids single or something that week, lol).
& yeah, full songs & singles aren't on iTunes. most fangirls buy the physical copies anyway, right? the bonuses are the sole reason i buy JE stuff.
it's true!
