Copy  the youtube http: code of song from youtube video you want to add

The go to this site and place the code in the box on top where it says

YouTube embed code or URL:

here is that site  https://www.tools4noobs.com/online_tools/youtube_xhtml/

After you put that code in that top box,  then put in width and height box at least 350 in both

Then I check   "autoplay" so it automatically plays if I want  it autoplay.

under that the only others I leave a check at is  "show Border"

and  "control"

Then just click blue button  generate code

 you will then see the code  for the video.. copy and paste it on your page in profile settings in the section you want like music  or about me or which one you choose
