With Looking Glass you can control playback from the Music app and save the current track to your library. You can also search for tracks, albums, artists, playlists, and recommendations and start playing them right away.

The app can be reached from the menu bar or with the mini player and keyboard shortcuts, which you can customize from the Preferences window. The mini player window provides additional shortcuts:

• "s" or space bar: toggle playback
• "a" or left arrow: jump to previous track
• "d" or right arrow: jump to next track
• "l": love the current track and add to Library (if the the option is enabled from Preferences and you're running macOS 12)
• "r": reveal the current track in Music window
