Unfortunately, it doesn't seem to be working for me. I have loop, autoplay, even bigMode off and the playlist still won't continue through.

Same here, the playlist doesn't work with any combination of options.

Nope, you don't have to login; try this for example:

You can trigger 'autoplay' on and off, as well as Play Next to skip ahead a track without autoplay turning off on you.

Playlists still do not work with the latest version. I got them to work by changing

if(loop) {
handleWatchPagePlayerStateChange=function(state) {
 if (state == 0) {
   try {
    player.seekTo(0,true);
    player.playVideo();
   } catch (e) {
     if (watchIsPlayingAll)
       gotoNext();
   }
 }
};
player.addEventListener("onStateChange","handleWatchPagePlayerStateChange");
}

to

handleWatchPagePlayerStateChange=function(state) {
 if (state == 0) {
   if(loop) {
    player.seekTo(0,true);
    player.playVideo();
   } 
   if (watchIsPlayingAll) {
    gotoNext();
   }
 }
};
player.addEventListener("onStateChange","handleWatchPagePlayerStateChange");

I guess when you reload the player the event handlers get cleared.
