Not that anyone responded but I figured out the answers to my problems in the post a couple above. For Apple Music, I had to go to the Cast choice rather than Streaming in order to control it.
For the organization of my downloaded files, I had to add them to the Library before they were sorted. That works fine except for the process. I did not see any way to select all of my files to add to the library so I had to add them one by one. So either I missed how to do it easier or it is a miserable experience taking a few hours of repetitive actions.
