iHype, we don't need validation from a fully fledged fomo, let alone anyone that spends 30 minutes making tables in excel for SYG. We "stan" (I guess?) because we like her music amongst a whole variety of other musicians, her personality etc. Unlike the typical Katy stan our library consists of a wide range of music.
The exact question you posed can be applied to any of the forgotten fads with weak R&B music you stan for; virtually no one checks for them and most detrimentally they're boing. But personally you like them and that's all that matters.
