This extension allows you to embed beepbox songs by their URL inside of your HTML5 GMS 2 games. This will help keep your HTML5 final package size way down, since you don't have to include the sound files directly. This also allows you to modify tempo and song key on the fly.
This only works for HTML5 as it uses the beepbox JS library.
