^ decision of cos was performed but wasnt promoted as heavily as talkin' 2 myself.
My logic is to see the title of the single to determine which song gets promoted.
a lame logic though.
But there are also a lot other songs that doesnt have a PV!! Songs like until that Day..., Secret, MY ALL didnt have a PV. So i feel that asking why Life doesnt have a PV is like why I am born a male. It's the way it is.
