does anyone actually own the rarest of ayu singles?

[~K+]

As you might have noticed, all those limited singles are Album cuts, or released simultaneously with a new album. Album cuts generally don't sell much, but given Ayu's power at the time, selling out 300,000 of them wasn't much of a problem even with album cuts.

But coincidentially, it seems appears/kanariya/Fly high also had some great remixes -_-"

It was also when Ayu's popularity was really picking up rapidly, so those 3 sold particularly fast. [And AUDIENCE and Daybreak aren't all that hard to find given you know where to look]
