^That's an interesting theory, and I kinda agree with it. During my first years of fandom, her materials and lyric for me are one of a kind. It's so intense and powerful and it matches with the demand of my brain to listen to such music.
Idk how to say it but I felt like her materials especially since Love Songs (it's still the best from her 3 latest album so far) were half-assed or like unfinished products (e.g Tell All was a mixing mess for me). So I drifted away from her latest music even though I still love some like snowy kiss, Merry-go-round, Wake me up, and Return Road.
Maybe the fact that I changed and she changed and we're no longer as compatible as before (in terms of personal feelings and taste), that's what made me lost my interest.
And maybe, because I don't really dig the whole cutesy thing...? I mean an older woman can be cute like Kylie Minogue, she's cute but she's cute appropriately not like "Hey, I'm a higshchool girl!" things like that...or maybe because it's a part of Japanese culture I can never embrace
