Actually, the mini-album was already titled Secret and it had a .SWF file and all that just before the announcement that the album was to be made into a full one.
It was basically all of the singles, with 1 LOVE/momentum/JEWEL attached.. and then of course Secret wasn't in in initial tracklist. [probably mimicking the bonus trackiness that Memorial address had]
It was one of those things that happened, and then just as we found that out, the album was changed again.. much like how AT08 was a 2DVD and is now a 3DVD. I guess Ayu really likes waiting on information...
