I'm not sure...
It can depend on the situation or fanbase or company and a whole lot of stuff.
Undertale, for example (casually sneaking in a thing I like lol) had a demo and kickstarter page a couple of years before the actual release date. That was not only to keep the hype going but to help fund the project.
I can think of examples where the opposite could work as well, but I can't really think of real life examples of it. But I know it is definitely something that happens!
So I disagree because the opposite of that statement can be true.
Considering music as an art form is very subjective, music rating websites are a very odd thing to exist.
