So she's replaced Kumi as the Honda CM girl ?
Anyway, Ami has been working on this album for a while. At a DJ gig in july/august (forgot when) her and Nakata performed a few untitled songs from it.
Plus can't stop the DISCO was already recorded in July, it's strange it took them way over a month to announce that that was the second single; I assume they'd planned for another song that wasn't ready in time or something.
