Becouse they're playing a runthrough.
glitter/fated isn't even listed under 浜崎あゆみ on Space Shower TV website yet. I've checked M-ON, but they're also missing glitter/fated in their listing of Ayu PVs (
http://www.m-on.jp/artist/6/detail695.html).
Her PVs usually air 1-2 weeks before the release they're from go on market, so I guess we still have to wait a few days at least...
