There’s lots of licence-free music websites around such as audiohub the main caveat is that you use their copyright or attribute the website etc
I’ve published Youtube videos with music by other artists in the video and have received emails from Youtube saying:
"A copyright owner using Content ID claimed some material in your video.
This is just a heads up. Don’t worry. You’re not in trouble and your account standing is not affected by this.
There are either ads running on your video, with the revenue going to the copyright owner, or the copyright owner is receiving stats about your video’s views.
If there are no problems, you don’t need to take any action. You don’t need to delete your video."
And I’ve never had any come back. So I wouldn’t worry unduly about using songs that your members really like and then publishing a video on Youtube of the session so that other members/people can view it.
Hope this is useful
