If the author sees this: with yt-dlp you can download lower quality versions of videos to save bandwidth, like so:
yt-dlp -f "bv[height<=720]" <url>
That will download up to 720p quality.
The author mentions just downloading the audio track. That's a lot less data than downloading any video at all. ;)
