Mark license as MIT in js so libreJS knows it is free js.

This will make it so libreJS will load the js on your page. I was going to make a pr, but saw you were not using standard html/ js and do not know how to use what you are using.

The first method on the below site is not the best, if beepbox links to external js hosted on beepbox, or a script tag, use this method on the page: https://www.gnu.org/software/librejs/free-your-javascript.html#magnet-link-license

Beepbox uses the expat variation of the MIT license.

See here for the librejs instructions for this: https://www.gnu.org/software/librejs/free-your-javascript.html
