Identical files in two locations needed to play music loaded at runtime?

Hi, I've written a test program that loads .mp3 and .ogg files from a folder outside of the Unity Assets folder. Users can add their own music to the folder, and a GUI button will pop up with the file name; click and play. This works well, (the .mp3s only load in the executable) except that I need to have each file in the "Music" folder I created, as well as the current directory of the exe.

Perhaps I'm doing something stupid in my code, or Unity will only load files in the same directory as the exe during runtime.

Here's the script:

     void Start () 
     {
         ReadDirectory();
     }
     
     void ReadDirectory()
     {
         string path = Directory.GetCurrentDirectory()+ "\\Music\\";
         DirectoryInfo info = new DirectoryInfo(path);
         testDirectory = path;
         FileInfo[] fileInfo = info.GetFiles();
         
         foreach (FileInfo file in fileInfo)
         {
             string filename = file.ToString();
             if (filename.Contains(".mp3") || filename.Contains(".ogg"))
             {
                 fileList.Add(filename);
                 filename = filename.Replace(path, "");
                 filename = filename.Replace("\\", "");
                 abbrevFileList.Add(filename);
             }
         }
     }
 
     void Update () {
         if (audio.clip)
         {
             if (!audio.isPlaying && audio.clip.isReadyToPlay)
             {
                 audio.Play();
             }
         }
     }
     
     void OnGUI()
     {
         // to see that the directory is correct and allow a way to close the application
         if (GUI.Button(new Rect(Screen.width * 0.4f, Screen.height * 0.3f, Screen.width * 0.2f, Screen.height * 0.05f), testDirectory))
         {
             Application.Quit();    
         }
         
         // select file
         for (int i = 0; i < fileList.Count; ++i)
         {
             if (GUI.Button(new Rect(Screen.width * 0.4f, (Screen.height * 0.4f) + (((float)i) * (Screen.height * 0.1f)), Screen.width * 0.2f, Screen.height * 0.05f), abbrevFileList[i]))
             {
                 WWW www = new WWW("file://"+fileList[i]);
                 if (fileList[i].Contains(".mp3"))
                     audio.clip = www.GetAudioClip(false, true, AudioType.MPEG);
                 else
                 {
                     audio.clip = www.GetAudioClip(false, true, AudioType.OGGVORBIS);
                 }
             }    
         }
     }
 }
