Ayu's song called "Memories"

[Tasked]

What do you think happened to this song? When Moments was about to be released, Moments was arranged by a guy named HIKARI. HIKARI was on a website where it said something like:

HIKARI'S ARRANGMENTS:
Hamasaki Ayumi - Moments
Hamasaki Ayumi - Memories

It was, of course, posted on all site's (AHS thread: http://www.ahsforum.com/forum/showthread.php?t=14841), and because it was an official site, it wasn't tagged as rumour and I don't think anyone every doubted it...
But of course, it was never released.

Was it a mistake, was it a song that never got released, or was it released afterwards under a different name? Your though please!
