从SoundCloud下载带有标签的音乐，获取标签

我有一个从Soundcloud获取歌曲的网站。我的问题是，所有下载的文件都有类似aline的名称！例如，如果我下载/获取文件"I walk alone-green day.mp3"，下载后它看起来像bybbydsbaubx.mp3。该怎么办？我只需要歌曲名称，因为我所有的用户都很困惑。

这是我的网页代码示例。

 <?php


include'func.php';
$id=$_GET['id'];
$grab=json_decode(ngegrab('http://api.soundcloud.com/tracks/'.$id.'.json?client_id=c435ec96ae345d5ce32496d339fc291d'));
$duration=format_time($grab->duration/1000);
if(!empty($grab->genre)){
$genre=$grab->genre;
}else{
$genre='Unknown';
}
$name=$grab->title;
$size=format_size(getfilesize(getlinkdl($id)));
if(!empty($name) && !empty($_GET['id']) && !empty($_GET['permalink'])){
$title='Download '.$name.' ('.$size.')';
