Apple Music and Apple TV authorization issues on Windows

Both Apple Music and Apple TV apps on windows keep not authorizing because "your password was changed, log out and sing back in" over and over. I have tried to no avail on multiple devices to make this work first try. I have been unable to authorize one computer without this issue. I have deauthorized all my computers. On one computer that I did get it to work but that was after removing every single thing on the computer's hard drive, registry keys and hidden files and folders that had apple in it. After reinstalling the apple music app, I got it to work.

Tried the same thing on my main computer but it still failed. So, I reinstalled iTunes, authorized it, and then install the Apple Music app and it was authorized.

This shouldn't be happening. Apple get your act together. Why can't we just keep iTunes? Why force us to have to open multiple apps to find our media. This is why I use Plex. Everything in one place, except all the music I previously purchased in iTunes.

Back to the problem. Please fix authorization. I know I changed my password. I specifically did that because it seemed to have been hacked. But now please make your apps work.
