If it was something that required a paid subscription for content they'd have set it up that way.
The fact as you know it is anybody can look up the song on YouTube and they themselves have a Share link. You can copy link, you can post to Facebook etc.

Post in your own name unless you're banned and can't. That could be it. In which case you shouldn't be here at all
