MPZ

If you like to organize your music in folders, then this player might be for you. It doesn't try to index all the files into a library, but rather treats your files and folders as a library and provides a convenient way to create playlists directly from folders. Similar to Foobar2000's Album List, but it's not an attempt to clone.

In about 15 years author couldn't find a suitable player for Linux. Foobar2000 works in Wine, but this solution is not perfect either. This player is an attempt to create the "perfect" player for the author. It doesn't have anything "breakthrough", it just gets the job done. The main feature is 3-columns UI and the way you manage playlists. Chose library folders, middle-click on a folder and a playlist will be created from this folder.

Why "big local collections"? "Local" opposed to streaming services (which are fine, but this player's goal is to play music you own, not rent), "big" means it's big enough so managing it becomes hard. Features

3-columns UI which allows you to quickly create playlists from folders and switch between playlists; Built with C++/Qt - fast and responsive native UI; Supports internet radio in m3u and pls playlists formats; Supports CUE sheets; Supports MPRIS on Linux for remote control (for example, via KDE Connect); Configuration in 2 yaml files: one for global (portable between computers) and one local (for settings specific to the current installation).

Limitations

Uses external codecs installed on your OS (through QtMultimedia, using GStreamer backend on Linux); Lacks some "expected" features like tracks rearranging within playlist; Global hotkeys don't work in Wayland.
