Paused:

Click on the bar toggles the playback. It is also possible to setup shortcuts to play next/previous track and toggle the playback - see below.

• install Hammerspoon - a powerfull automation tool for OS X

  • Manually:

    Download the latest release, and drag Hammerspoon.app from your Downloads folder to Applications.

  • Homebrew:

    brew install hammerspoon --cask

• download music-now-playing.spoon, unzip and double click on a .spoon file. It will be installed under ~/.hammerspoon/Spoons folder.

• open ~/.hammerspoon/init.lua and add the following snippet, adding your parameters:

-- music now playing
hs.loadSpoon("music-now-playing")
spoon['music-now-playing']:start()
spoon['music-now-playing']:bindHotkeys(
  {
    next={ {"ctrl", "alt"}, "Right"},
    prev={ {"ctrl", "alt"}, "Left"},
    playpause={ {"ctrl", "alt"}, "p"}
  }
)

The config above sets up the following shortcuts:

• Ctrl Alt → - play next track
• Ctrl Alt ← - play previous track
• Ctrl Alt P - play/pause
