MusicBee by Steven Mayall is a freeware music organizer that will let you browse, organize, tag, play and find music not only on your computer, but also on other devices. Sadly, it is not known when (if ever) MusicBee for Mac will be released. However, you can use several other applications instead. These programs can perfectly replace MusicBee for Mac and do the same job perfectly well.
Feel free to add any alternative to MusicBee for Mac that you know of.
