I tried to use the YT bbcode to wrap the playlist, but nope - didn't work.
Stevie Ray explains the way to use the YT bbcode, but I sense you already have that science figured out.
So, I think the best thing to do is just point to the playlist
Era - Come Into My World - YouTube
I just pasted the URL into this post and the forum added the text (if you have Automatically retrieve titles from external links ticked below in Additional options of a post.)
I guess that will play the whole list - sure why not, it's just a link.
