Agreed. Losing that and coverflow leaves iTunes with just the annoyances.
MusicBee on Windows works better than most everything else, and keeps the three column view as one of the many options. Haven't found anything I can live with on the Mac yet.
Never saw the point in Finder windows though, preferring the default, or two linked folders in one OS window like DirectoryOpus (Amiga and eventually Windows) and most ftp clients used to do it. That's better when needing source/dest, or diffing two folders etc.
OneCommander makes for a nice combination of Miller columns and [orthodox file management](https://en.wikipedia.org/wiki/File_manager#Orthodox_file_man...) (the two side-by-side directories, i.e. what DOpus uses as its layout). Quite a few GUI (S)FTP clients still use the orthodox layout as well.
