It's possible the youtube link is not available in your country. Please ask the person for a link and see if it loads in your web browser of choice.

It is also possible the youtube player's volume is muted in Edge/IE, so check that.

I've been wondering if you would consider using some other source for BGM links. (i.e. grooveshark was a thing a lot of players used pre-GR). While youtube is very convenient they've started cracking down on copyright issues quite badly. If it's troublesome I totally understand.
