Mp3 id3 tag

Koristim ovaj kod za čitanje id3 podataka mp3 file-a.

Problem je što mi vrati tekst samo za Comment polje.

Zašto ne vraća i druga polja?

using (FileStream fs = File.OpenRead(mp3File))

       {

         if (fs.Length >= 128)

         {

           MusicID3Tag tag = new MusicID3Tag();

           fs.Seek(-128, SeekOrigin.End);

           fs.Read(tag.TAGID, 0, tag.TAGID.Length);

           fs.Read(tag.Title, 0, tag.Title.Length);

           fs.Read(tag.Artist, 0, tag.Artist.Length);

           fs.Read(tag.Album, 0, tag.Album.Length);

           fs.Read(tag.Year, 0, tag.Year.Length);

           fs.Read(tag.Comment, 0, tag.Comment.Length);

           fs.Read(tag.Genre, 0, tag.Genre.Length);

           string theTAGID = Encoding.Default.GetString(tag.TAGID);

           if (theTAGID.Equals("TAG"));

           {

             string Title = Encoding.Default.GetString(tag.Title);

             string Artist = Encoding.Default.GetString(tag.Artist);

             string Album = Encoding.Default.GetString(tag.Album);

             string Year = Encoding.Default.GetString(tag.Year);

             string Comment = Encoding.Default.GetString(tag.Comment);

             string Genre = Encoding.Default.GetString(tag.Genre);

             lblTitle.Text = Title;

             lblArtist.Text = Artist;

             lblAlbum.Text = Album;

             lblYear.Text = Year;

             lblComment.Text = Comment;

             lblGenre.Text = Genre;

           }

         }

       }
