Javascript Random Music Player Options

[RobGoldy]

I am trying to make it so that when the page loads, it will random play a song from a list of songs. Also, when the first song finishes, another random song should play. I have this code:

CODE

<script type="text/javascript">
var numberOfSongs = 5
var sound = new Array(numberOfSongs+1)
sound[0]= "music/Rock/1.mp3"
sound[1]= "music/Rock/2.mp3"
sound[2]= "music/Rock/3.mp3"
sound[3]= "music/Rock/4.mp3"
sound[4]= "music/Rock/5.mp3"
sound[5]= "music/Rock/6.mp3"


function randomNumber()
{
var randomLooper = -1
while (randomLooper < 0 || randomLooper > numberOfSongs || isNaN(randomLooper)){ randomLooper = parseInt(Math.random()*(numberOfSongs+1))
}
return randomLooper
}


var soundFile = sound[randomNumber ()]
    document.writeln ('<BGSOUND SRC="' + soundFile + '" loop=5>');
    document.writeln ('<EMBED SRC= "' + soundFile + '" loop=5 PLAYCOUNT=3 hidden=true autostart=true><P>');
</script>

How would it be possible to play another random song after the song finishes?
