I'm with j_nerd.

And i'm more inclined to believe this is real and not fan-made; on LOVEppears there were also alot of album mixes with only slight tweaking from the single versions. I can think of two reasons this could be; either because ayu was somewhat dissatisfied with the original, or because they lost the master copies of the original mix and had to get someone to come in and mix it all over again.
