Yt-dlp: External JavaScript runtime now required for full YouTube support

I use yt-dlp (and back then youtube-dl) all the time to archive my liked videos. Started back in around 2010, now I have tens of thousands of videos saved. Storage is cheap and a huge percent of them are not available anymore on the site.

I also save temporary videos removed after a time for example NHK honbasho sumo highlights which are only available for a month or so then they permanently remove them.

Same here and my motivation was that some of my liked videos were randomly removed and it's pretty cool music I wanted to keep forever.

I made another script that adds the video thumbnail as album art and somehow tries to put the proper ID3 tags, it works like 90% of the time which is good enough for me.

Then I made another script that syncs it to my phone when I connect it.

So now I have unlimited music in my phone and I only have to click on "Like" to add more.

And yet, none of Google's 900k TOC genius engineers have thought of this as a feature ...

Isn’t that the YouTube Music app?

No.

How so? What’s missing?
