It’s the playlist link that’s the problem. It ends with playlist?list=LM
which stands for “Liked Music”. The downloader doesn’t know your account’s liked music playlist. It needs a playlist ID like playlist?list=PLO7q4X25LQEEyJAQe5EEwJxUCSKvuKbok
Basically you need the songs to be in a different playlist
It’s not the ads I hate, it’s the data harvesting I hate. Static ads without trackers don’t exist on YouTube, unfortunately.
