How can I generate a random audio player?

I've tried this but it didn't work, plz h !!!

let audioSrcName = ["sam1.mp3","sam2.mp3","sam3.mp3","sam4.mp3","sam5.mp3"];

var randomSong = audioSrcName[Math.floor(Math.random()*audioSrcName.length)];

var audioElement = document.createElement('audio');

audioElement.setAttribute('src', randomSong);

document.getElementById("rand").appendChild(audioElement);

for the html, I just create a div with id ="rand".
