I did that. I deleted the entire old MusicBee folder. When I opened MusicBee again, it prompted me to "Choose Music Library". I deleted the old path and created a new library. When MusicBee launched, it showed a new album with no tracks in it. So far, so good. Then, I selected "Scan Folders for New Files". in the new dialog box, I navigated to the new folder, and click "Proceed". MusicBee then scanned for new files. When it was done, it again showed the two albums, one is with all of my tracks, and the one is "empty", but has seven tracks.
