Google does not have a public api for Google Music. As a consquence using this script violates the Google's terms of use. You have been warned. In order to make requests we must spoof a device that is already connected to your Google Music account. Fortuantely our Google Music library, simon-weber/gmusicapi, does most of the work. The easiest way to get a device id is for you to supply a dummy one on the command line, this will crash the app, but Google returns your device IDs in the error message (nice).

1. Visit your spotify developer dashboard
2. Create an app, the Client ID and Secret Should be immediately visible
3. Click "Edit Settings"
4. Add "http://localhost/" to "Redirect URIs". During the first execution of the script this will open your browser, authenticate you with Spotify then redirect you to "http://localhost/?code=...". Copy this URL (yes the entire thing) into your terminal when prompted.

Spotify and Google Music don't exactly see eye-to-eye on what they consider ways to favorite a track. Google allows you to "thumbs up" tracks that you like. Spotify allows you to save tracks you like and add them to playlists. When you save a track or add it to a playlist Spotify infers that you like the song. To import your Google "thumbs up" I recommend creating a new playlist from your "thumbs up"ed tracks. Unfortunately the pre-created auto playlist is not accessible from outside of an official client so you will need to export these to a new playlist. To do so, go to your "playlists" page in Google music find "Thumbs up" in the "Auto-playlists" section. Mouse over it, and click the three-dots menu, select "Add playlist to playlist" > "New Playlist". When you specify --favorites-playlist make sure to supply the same name (capitilization matters!).
