Audio Streaming Not Working

So I'm trying to get personal Audio loading working where people can play their own music, but I ran into a few problems with an overly complicated script (which automatically gets the file-path) so I stripped back the code to find out what the issue was. Here is the code:

 var Source1 : GameObject;
 var url : String;
 
 function Start()
 {
     var www = new WWW(url);
     Source1.audio.clip = www.GetAudioClip(false,true, AudioType.WAV);
     
     if (System.IO.Directory.Exists(MusicFolder)) {
     } else {
     System.IO.Directory.CreateDirectory(MusicFolder);
     }
     
     
    }
    
 
 function Update () {
     if(!Source1.audio.isPlaying && Source1.audio.clip.isReadyToPlay)
         Source1.audio.Play();
 }    

I have used a screenshot of the Source1 GameObject too help. The url variable is set to:

 J:\13 DESIGNED GAMES $$$$$$$$$$$$$$$\FULL GAMES\GREEBROLL\Greebroll Menu\MenuAmbience01.wav

Here is a screenshot of the actual filepath: When I press play, the Audio Clip variable on the Audio Source component on the Source 1 Gameobject is blank (doesn't state MenuAmbience01) instead it just has the small audio icon. Help would be greatly appreciated.
