To clarify a few things. Dearest is not copy-protected, the scheme wasn't introduced until sometime in 2002, Dearest was released on 2001.09.27. (I only remember this date because 3 items was released on the same day
)
"Dearest- Acoustic Piano Version" is
not limited, it's only a bonus track that should be on all discs. However, soon after it was pressed it's been announced that there was defect batch in the market without the bonus track.
And yesasia wouldn't write back, there's a policy on their Help page, if you have a defect item, you can try to send it back and ask for an exchange, but you pay for your own shipping. They never bothered to reply me when my MISIA single was missing 2 tracks.
