Hey everyone, I came across something interesting and was wondering if anyone has more info about it.

Apparently, if you add UL0123456789w as a playlist code in any YouTube video URL, like this:

https://youtu.be/NhheiPTdZCw?list=UL0123456789w

It creates a full channel playlist in chronological order.

This is different from the usual channel playlists that have codes like:

Which are annoyingly in reverse chronological order.

I am not sure how I discovered this code, it was just attached to a video
