Youtube question - Add to Watch Later playlist on the fly
Here's the problem. I want to have a tab open that's playing a youtube playlist and automatically moving to the next entry as each one finishes. Then I want to be able to append new tracks onto the playlist from another tab(s) on the fly and have them played when the playlist reaches them.

I can almost do this with the Watch Later function. The problem is that when the playlist tab reaches the end of what it thinks is the end of the list, it refreshes the page and gets the new entries but it loops back to the beginning.

Pretty much all music playing systems have the concept of a playlist that you can add to on the fly. Usually called Enqueue, or Add to Playlist or On The Go or something. Perhaps I'm missing something in Youtube or there's another clever technique to doing this but I can't seem to make this work. This is becoming important because increasingly youtube is where you find a stream of new music.

Of course what I'm also trying to create like this is effectively a free (ad supported) version of Spotify.
