This is annoying because I don't want a new song to start playing after I heard what I wanted to hear and I think a lot of people would agree.
My problem is not that I can't turn it off at all, but it keeps switching back on whenever I refresh the page or get rid of the tab and come back.
It's annoying me. If this is an intentional thing, please tell the devs to change this.
In that case, YouTube already has this feature AND autoplay STAYS off when you want it to. Be like YouTube.
