You've created 12 forum threads in less than a month, almost all of them are Cave Story theories.
Forums aren't really a place where you can quickly start a topic, discuss it for a bit, and move on.
Firstly, some of the questions you've asked have already been answered in older threads, so you should look in the Theories Category or search for it (above right corner). Secondly, there are Discord servers that
are meant for quick discussion of topics, you should probably talk more there. (Discord is a downloadable chat client, people are
way more active there, by the way.)
This site's Discord server link:

At the very least, you can post questions in the Profile Posts. But, again, be careful and don't overdo it (and by being careful I don't mean "post a bit less". Make your topic worth it.)
There's also a problem with your
customized soundtrack. I need to repeat what has been said: Copyright does not work like you think it does.
Nothing's restricting me from using them in the first place. No copyright in the music, no trouble.
Copyright has always been there, it's stated everywhere if you look at the game, or its cover, or its title screen, or the site of its publisher, or... well, you get it. Just because you can maybe download it from Youtube doesn't mean it's legal, or okay to do.
Posting it online for everybody else to download is even worse.
Sure, the companies might not care for one person doing that.
But if they do, the entire forum would be responsible, which is not very nice.
Also, that's just piracy, do you know how much effort is put into making music? The musicians deserve some money for their works, at least.
What I'm trying to say is: don't just create entire threads every time something about Cave Story bothers you. You should search more.
