I have been on the Synapse HDD path. It was slow even for a single-user instance.

Guess we’re sharing scripts now. I have a script that downloads playlists as MP3s and keep an archive.

#!/usr/bin/env sh

browser_cookies="firefox:1cvnyph7.YouTube TV"

download() {
	url="https://www.youtube.com/playlist?list=%241"
	dir=$2
	archive_name=$3

	yt-dlp -x --audio-format mp3 --embed-thumbnail --embed-metadata --cookies-from-browser "$browser_cookies" --download-archive "archives/$archive_name.txt" -P "$dir" -o "%(title)s.%(ext)s" "$url"
}
