How so? Vocaloid already exist for nearly a decade, back then many are worried that it will replace real human singers (because why hire singers when music composer can just use their computer?)
Fast forward today, pretty much only Japanese that still use it. Even during the height of it's popularity, it didn't even manage to "fully replace" human singer.
Didn't they already try something similar to this, was it Discord Game Store or something? That end up in failure.
