Force mp3 download using header()

[Yrogerg]

I'm trying to force the browser to download an *.mp3 file on the server and I've got the 'Save to your computer' dialog box to come up but when I choose 'Save' it doesn't download the file correctly. It takes literally 1 second and the file is incomplete.

Here's what I've got:

<?
// http://www.mydomain.com/download.php?type=song&track=01

switch($type){
	case "song":
		switch($track){
			case "01":
				$file = "Awake%20-%20Everything%20For%20You.mp3";
				$path = "http://www.mydomain.com/audio/Awake%20-%20Everything%20For%20You.mp3";
				header("Content-Disposition: attachment; filename=$file");
				header("Content-Type: " . filetype($path));
				header("Content-Length: " . filesize($path));
				readfile("$path");
				break;
			case "02":
				$file = "Awake%20-%20Second%20Place.mp3";
				$path = "http://www.mydomain.com/audio/Awake%20-%20Second%20Place.mp3.mp3";
				header("Content-Disposition: attachment; filename=$file");
				header("Content-Type: " . filetype($path));
				header("Content-Length: " . filesize($path));
				readfile("$path");
				break;
		}
		break;
}
?>

$file = "Awake%20-%20Everything%20For%20You.mp3"; 
$path = "http://www.mydomain.com/audio/Awake%20-%20Everything%20For%20You.mp3";
$fp = fopen($path,'rb');
header("Content-Disposition: attachment; filename=$file"); 
header("Content-Type: " . filetype($path)); 
header("Content-Length: " . filesize($path)); 
fpassthru($path);
