Apple Music for Mac has stopped allowing me to add music
Music for Mac was working great until about 2 months ago. I can't add MP3 files to the library or play them directly from the desk top. I've tried to drag and drop files. It will appear with plus icon like it's working but nothing happens. I've also tried a right click, open file with "Music" and nothing happens. File will play with Quicktime, VLC, etc. Just stopped working with Music. I tried upgrading my OS, searching for a app update, hard restarts. I have MacOS Monterey now, but the problem started with my previous OS.
