Do something like:

        protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);
            GetOggDirectories ("/");
        }

        IEnumerable<string> GetOggDirectories (string path)
        {
            foreach (var dir in Directory.EnumerateDirectories (path))
            {
                if (Directory.GetFiles (dir, "*.ogg").Any ())
                    yield return dir;
                foreach (var sub in GetOggDirectories (dir))
                    yield return sub;
            }
        }

This (likely) causes UnauthorizedAccessException (if there are
access-unauthorized file).

This makes Directory.GetFiles() kind of useless.

(Is it consistent with our usual behavior on linux?)
