Setup

1. Enable YouTube Data API v3 in your Google API console
2. Get Google API OAuth 2.0 credentials with the scope "youtube.force-ssl"
3. Save client ID and client secret into client_secrets.json (see SAMPLE_client_secrets.json for the format, couple other things that need to be there)
4. pip install -r requirements.txt

Probably needs Python 3.something

Usage

With a playlist.txt file looking like this:

https://youtu.be/eB9n7vuPBxk
https://youtu.be/sXoC2fXFGwg
https://youtu.be/pRWh7NaeDlM
https://youtu.be/LkMxDj8qJNQ

https://youtu.be/CaRXfTXOGJI
https://youtu.be/1b5iBmwbF1k

Run python playlist-maker.py PLAYLIST_ID where PLAYLIST_ID is the ID of the playlist you wish to add the songs from playlist.txt to.

Console will ask you to load a URL to authorize your YouTube account, and you'll need to copy a code into the console after it's done. Make sure you're signing into the right account that owns the playlist - some Google accounts will have two different YouTube identities and you'll get 403 forbidden playlistItemsNotAccessible

With any luck, it'll add songs to the playlist until it reaches the end of the file or you run out of your quota
