Ayu Conundrum... あゆの新シングル(s)

I went to Mongkok last night after work and stopped by a CD shop.  I found that they were selling Hamasaki Ayumi's new single that was released in Japan last week:


let me zoom in a bit:

It says something like "celebrating 10 years since her first single,  her second wave single"

Often times Ayu releases two new songs together into one CD single,  and titles the disc with the name of the two tracks separated by a hyphen (ie 'Glitter / Fated' , etc).

But whats the deal with these new songs?  There's actually two singles? 


One is called 'Days / GREEN' and the second is called 'GREEN / Days' 

Hmm...   let's take a closer look:

As the descriptive labels clarify - they have different versions.  Just a CD that sells for HK$49 (about US$6.50) and a CD+DVD that sells for HK$65 (about US$8.25)....

OK, so it must be that they're identical but just two different covers?  And you can get either w/o or without the DVD?

No!  take a look at the track list:


Days/GREEN  CD:
01.  Days (Original mix) 
02.  GREEN (Original mix) 
03.  LOVE ～Destiny～ (10th Anniversary version)
04.  Days (Original mix -Instrumental-)
05.  GREEN (Instrumental -Instrumental-)
06.  LOVE ～Destiny～ (10th Anniversary version -Instrumental-)

Days/GREEN DVD:
01. Days (video clip)
02. GREEN (video clip)
03. Days (making clip)


vs

GREEN/Days CD:
01.  GREEN (Original mix) 
02.  Days (Original mix) 
03.  TO BE (10th Anniversary version)
04.  GREEN (Instrumental -Instrumental-)
05. Days (Original mix -Instrumental-)
06. TO BE (10th Anniversary version -Instrumental-)

GREEN/Days DVD:
01. GREEN (video clip)
02. Days (video clip)
03. GREEN (making clip)

(not sure what an 'Instrumental -Instrumental-' is...)

ALMOST the same... they're really tricky! 

One version has the new songs 'GREEN' + 'Days' + the 10th Anniversary Version of 'Love ~Destiny~'.  The other one has 'GREEN' + 'Days' + the 10th Anniversary Version of 'To Be'.  

Each one has a different 'anniversary version' song -- a re-recording of an old school Hamasaki Song.  'Love Destiny' and 'To Be' were her first two #1 Singles from 1999.
