HTML 5 Audio Tag Multiple Files

In javascript you can do it like this (this is just to get you started):

audio = new Audio("start url");

  audio.addEventListener('ended',function(){
        audio.src = "https://stackoverflow.com/questions/18274061/new url";
        audio.pause();
        audio.load();
        audio.play();
    });

if you want you can also use the same player(jquery):

var audio = $("#player");
