A music client for Subsonic-compatible servers (Navidrome, Gonic, ...) and Music Assistant: browse artists, albums, album lists and podcasts, search, and manage a play queue from Emacs. Playback happens locally through mpv, or remotely on the Subsonic server's jukebox, a UPnP/DLNA renderer or a Music Assistant player. Start with `M-x supersonic'; see the README for configuration. mpv is driven over a Unix-domain socket, so local playback does not work on native Windows.
