A few python scripts to download liked music from ytmusic or add all liked songs to another playlist. Now with the ability to move songs over from spotify to youtube music! Each folder has all the files needed to run self-contained. The only setup required is to set your own cookies in the headers_auth_example.json file, rename it to just headers_auth.json and install ytmusicapi. If you need spotify features you need to install spotipy and set the API data in a spotify_secrets.json, same way as with the youtube stuff, but this time they can be generated here. More info can be found in the official ytmusicapi page.
