mind soothing audio clip downloader

i was searching for some mind soothing audio tracks. and came across a web site with an embedded player. the experience was not that good as the player pauses few times during a track to buffer the clip.

the result was this, a small php script to fetch the tracks to my server ;)

$i=1;
while($i < 13){
        $feed = fopen('http://www.freesoothingmusic.com/category_playlist.php?cat_id=' . $i, 'r');
        $contents = stream_get_contents($feed);
        $dom = new DOMDocument;
        @$dom->loadXML($contents);
        $xml = @simplexml_import_dom($dom);
        fclose($feed);
        $trackCount = sizeof($xml->trackList->track);
        for($j=0; $j < $trackCount; $j++) {
                $fileLocation = $xml->trackList->track[$j]->location;
                echo exec('wget ' . $fileLocation);
        }
        $i++;
}
