Dragging (copying) music from Music app in Catalina (formerly iTunes) to a Finder folder is actually moving files.
I really don't understand what's happening. I've tried this a few times. I used to drag MP3 music files all the time from my music library in iTunes (now Apple music app) to a folder and it is suppose to copy the files, but now when I try to play the song again it's lost and can't find it meaning the original file is being moved and not copied. When the little status window pops up it says it's copying the files, but it really is moving them. This is ridiculous.
I'm glad I have backups, but I have years of music files that I purchased and converted to play in other devices when I don't have bluetooth or internet connection available. I'd like to have these files because you never know what will happen to the way we hear music in the future. I'm old school.
