music folder in my music folder

Although this question seems to have been asked previously, I think it pertinent to ask it again. Back in September of 2015 my hard drive crashed and, although I had all of my stuff backed up, the tech guy was able to salvage most of my stuff and everything seemed to be ok. But I noticed that, for some reason, I had multiple copies of songs in my library, like 5 and 6 and sometimes 10 copies of the same song. So, I went on a mission. I opened up my music folder and went artist by artist, group by group, including folders like various artists, unknown artists, compilations, and so on, and manually removed every single duplicate. That took until a few weeks ago. So now everything is cleaned up.

My music is stored in a manner similar to my other folders like "my pictures", "my documents", that is, the primary folder is on my desktop. You double click to open it and the folders of all the artists are stored within it, and are all displayed alphabetically. So, if I purchased music from iTunes for a group that I don't already have on my computer, I simply want those artists, with their respect folders, to appear within the general music folder called "music" (my actual folder on my desktop is called "music - shortcut").

However, when I download music from iTunes, those artists are downloaded to a folder inside my desktop "music shortcut" folder, which adequately and confusingly enough is also called "music". Now, the benefit of this is that I can always very quickly find the latest music files that I have downloaded, because they always go into this odd "music" folder. But, me being partly obsessive/compulsive, that will bug me because now the same artist can potentially exist in two places; the main folder where I want everything filed, and this newly added "music" folder from iTunes.

In order to correct the problem, I have to manually open up this weird music folder, and, if it's a group I don't have, simply cut and paste it into the general folder. But if it's a group I already have, I have to cut the album or song, then go find the group or artist, open that file, then paste it. It's a pain.

Now for my question. Is there a way to permanently get rid of this "music" folder that iTunes is making every time that I purchase a song? To help, I have NOT check off "keep iTunes media folder organized" and I do NOT have checked off "copy files to iTunes media folder when adding to library". This is because I don't not ever want to have duplicate copies of any song on my computer ever again!!!!! Just the main folder, the group or artist folder with in it, the albums within that, and the songs. My file folder destination is: C:\Users\Derek\Music. Based on this destination, you would think that the artists that are downloaded would be going to the place indicated. But no. It's almost like it's going to C:\Users\Derek\Music\Music, but I don't have it presented that way.

Help please, and please note, I'm 47 years old and not really a tech person. I'm a high school math, science and phys ed teacher but you need to explain everything in simple, easy to follow language with appropriate sentences or I probably won't be able to follow your implicit instructions. I thank you in advance for your assistance.
