now-playing.el is available to install from MELPA (TBD).
For manual installation, ensure that now-playing.el is available in the Emacs load-path variable.
now-playing.el will take advantage of the macOS SF Symbols font. Use the convenience command now-playing-init to setup both SF Symbols and to globally set your keybinding preference to the Transient menu now-playing-tmenu.
Interactively run M-x now-playing-init or add the following line to your Emacs initialization file:
(now-playing-init "<f14>")
Alternately, a direct setting of your keybinding preference to now-playing-tmenu can be done as follows:
(keymap-global-set "<f14>" #'now-playing-tmenu)
