I have a feeling there're no additional pictures inside the 4 different editions of Shhh! , I could be wrong I don't know
Honestly , I'm not very motivated to buy them . I was tempted to buy the fanclub editions of HOTEL & Dance In The Rain as that time when both were released , I was unsure if the fanclub exclusive material will be included in WALK OF MY LIFE but luckily in the end I didn't buy them
But yeah the idea could have been more better executed and switching the tracklist wouldn't hurt to get more value from what you pay , like putting in the CD studio versions of Cupcake and/or BRING IT ON
It's like for the sake of getting the other 3 editions of Shhh! that can't be purchased online , you have to go to the KODA KUMI LIVE TOUR 2016 ~Best Single Collection~ concert venues to do so :x
Also I'm not sure how mean avex is but for other artistes , only if you have the concert tickets then you're allowed to buy but somehow I doubt so
