Music to array from specified path

I am making a music player, kinda. I have the filing working it will find the song in the specified file. I need to know how I could make it play the next song and I think it would be easier if we put it into an array?

 var MusicFolder : System.IO.DirectoryInfo;
 var myClip : WWW;
 var myPath : String;
 var playList : AudioClip[];
 
 
 var i : int = 0;
  
 function Start(){
     myPath = "/Entertainment/Music/Count Your Blessings";
     MusicFolder = new System.IO.DirectoryInfo(myPath);
     myClip = new WWW("file:///" + MusicFolder.GetFiles()[i].FullName);
     audio.clip = myClip.GetAudioClip(false, false);
     i++;
 }
 
 
 function Update(){
 
     if (!audio.isPlaying && audio.clip.isReadyToPlay)
     {
            audio.Play();
          i++;
     }    
     
   
     
 }
 
 function PlayNext (){
 
     if(audio.isPlaying){
         i++;
         MusicFolder = new System.IO.DirectoryInfo(myPath);
             myClip = new WWW("file:///" + MusicFolder.GetFiles()[i].FullName);
         audio.clip = myClip.GetAudioClip(false, false);
     }
 }
 
 function OnGUI () {
 
         var search : String;
         // Make a text field that modifies stringToEdit.
         search = GUI.TextField (Rect (10, 10, 200, 20),"myPath",  256);
 }
