        if (root.Lyrics3V2 == null)
        {
            root.Lyrics3V2 = new LyricsTag();
        }

        // Update lyrics data
        root.Lyrics3V2.Lyrics = "[00:01]Test lyrics";
        root.Lyrics3V2.Artist = "test artist";
        root.Lyrics3V2.Album = "test album";
        root.Lyrics3V2.Track = "test track";
