Thanks @Sighlass ! Like I said...my problems in posting are probably user related, lol, or possibly my ancient computer. That's why I don't post too often in the music forum. I don't feel like I am much of a contributor without links. 
At one time I had a season ticket to a place in Dallas that featured dancers from around the world. I loved it and saw sooo many good dancers. I don't know what it is..I see the dance, I feel the dance...but my feet don't, lol.
All good
@berdie.... Tom put a help guide on it somewhere....
I just copy the URL at the music video ... but it contains something that you have to change...
For example... here is a video on how to post in forum YouTube links...
https://www.youtube.com/watch?v=9YOSVTGu5hsBut notice it did not post where you could see the video... instead you probable got just a link you can click....
That is because it (the URL) is has Http
s at the beginning.... If I take out that little "S" then it shows up here like the below...
Error 404 (Not Found)!!1So
https://www(dot)youtube(dot)com/watch?v=9YOSVTGu5hs only gives the link in clickable form...
But
http://www(dot)youtube(dot)com/watch?v=9YOSVTGu5hs lets the forum post it as a view-able video....

Then you should be able to just paste the URL in reply box and remove the "S" and it shows up for us here to just click and play.
