^If she actually read all of them, them there most likely weren't that much of them. In other words, this wasn't something casual listeners were excited about.

This kind of promotional tatics work for those already converted, on the same way not releasing stuff for a longer time only impact those who already had a chance of buying her stuff.

IMO she is simply working with the fact that her fanbase is anxious for a new release by leading them into getting curious about this demo that magically appeared on her streaming profiles and summer playlist.

Considering the whole description of the playlist is in Japanese, this is not something done with her overseas fandom in mind and if her japanese fans speculating about it on social media bring attention for whatever new release she is clearly planing, the campaign worked.

It's not like she started this whole thing with the demo. She didn't release anything for longer than her usual, kept on hinting on social media that something will be released soon, is sharing videos from her record sessions with the public, etc. I remember someone saying on her social media thread that they would go into the studio way more confortable than she was if they were there to record music. She most likely does, when there isn't plans to film or photograph it for promotional purposes (and when she isn't being paid to wear ugly ass shoes to promote them :B)

The whole thing is pretty much a promotional effort aimed for the japanese public that follows her through social media and digital music plattaforms.
