Arguably they could put up Morning Musume before the name change as well but I honestly think they should do what they are doing with the shuffle/special units and dumping them all under the hello!project name. That seems a lot more sensible than creating a new “name” with every new year.
Unfortunately once they go public with the digital in international it seems to really screw with some of the song releases on Apple Music. Songs from W that were once available have since disappeared but seem to be available on Spotify. It’s all very confusing on they are handling these releases.
As an aside I would love for them to release the PETITBEST albums under the hello!project section. But I doubt they would until they released the active groups first.
