You know, if you had just posted some music with a description of this method which you used to write it, I doubt anybody would react negatively. It is acting as if you have the musical Theory of Relativity that is dumb, just begging for mockery on the internet. I'll stop using hyperbole for awhile. It isn't really plagiarism, although I would definitely be uncomfortable having the majority of what I write derived from other composers' music.
You see, normal people don't so this. They don't memorize and quote numbers of positive internet comments, as if anybody cares or as if it proves anything at all. They don't call their own music great or magic. Even if you think it is great, you don't say it. You are not the one doing us a favor by sharing whatever this is. We are the ones who are doing you a favor by actually reading it and giving opinions. There are plenty of people who have ideas and music to share, and we don't have to give a scraggy. You have things backwards. Consider the possibility that you are not special and this thing you came up with is nothing innovative.
Now I'll tell you why I think this is nothing special. The only thing new about what you have is that you use material from other composers' to build your music. This might be a good idea for several pieces, as a sort of homage to your favorite music, but using this as your primary tool would make me, at least, uncomfortable. You also have not explained how this makes music sound any better, or what it brings to the table that other methods don't. At this point I'm thinking nothing.
This doesn't even come close to deserving it's own fancy name, or a forum dedicated to it.
