Adds a checkbox bottom right, once enabled, it'll loop without it stopping
Its like the loop button from youtube music, but currently, youtube music's loop button is broken.
So, once you enable the checkbox bottom right, it'll loop any mp3 or mp4 or etc, even if you refresh or something, it remembers if you kept the button enabled or disabled, so yeah. plus its better than the loop button from youtube music anyway, sooo... yeah. Works really well.
