All of the above, lol.
I think it's gotten out of hand honestly. Yeah, the choice of album covers is usually pretty good but that's about it. There's barely any
real extras like actual B-sides and tons of interesting remixes like there used to be. Now it's Double A-side, the instrumentals and maybe some random track. It's infuriating how you used to get more for buying one single but now you're getting less for buying multiple singles. I mean, vogue had like 8 remixes, 1 b-side, and the instrumental and it was just a regular CD!
But hey, I don't blame them for doing it. The fans are the ones letting them get away with it afterall by buying all the versions. It's their money and their choice though.
As for me, I'm not one to usually buy singles (as they're usually a waste of money since they'll be on the album) but since RnRC turned out to be a bit of a disappointment, I've decided to purchase moon/blossom to welcome in a (hopefully) more satisfying era of Ayu music. And since it's the 3 single project until the big 50th single, I plan on buying all the other singles released this year as well since it's my assumption they'll do something special with all of them (bringing back the composer from ASFXX was pretty special imho) and just in case, I don't wanna miss out. It'll only be one copy and one version of each though.
The only other singles I will buy are Mirrorcle World (for obvious reasons), vogue (because I love everfree), and Days/GREEN (since it was a 10th anniversary single as well and a darn pretty one ^_^).
