Mp3 streaming problem in using NAudio

I am working on streaming mp3 from url source for a few days.It almost works good except a small problem. The problem is that there is some momentary interruptions while playing mp3. I couldnt figure out why this happening. I need help and my code is like that. Sorry it's too long but maybe you want to try.

private void buttonPlay_Click(object sender, EventArgs e)
        {
           

            string url = "http://freedownloads.last.fm/download/569264057/Get%2BGot.mp3";
            bool playingStarted = false;

            WaveStream str;
            WaveFormat format = GetWaveFormat(url);

            HttpWebRequest req = WebRequest.Create(url) as HttpWebRequest;
            HttpWebResponse resp = req.GetResponse() as HttpWebResponse;

            int contentLength=(int)resp.ContentLength;

            Stream stream = resp.GetResponseStream();

            BufferedWaveProvider provider = new BufferedWaveProvider(format);
            provider.BufferDuration = TimeSpan.FromMinutes(20);
            
            byte[] buffer = new byte[format.SampleRate];
            byte[] totalBuffer = new byte[contentLength];
            byte[] mp3StreamBuffer = new byte[format.SampleRate];
            
            int bytesRead = 0, totalBytes=0;
            int decBytes = 0;
            long skipTo = 0;
           
            Task.Factory.StartNew(() =>
            {
                while ((bytesRead = stream.Read(buffer, 0, buffer.Length)) > 0)
                {
                    Buffer.BlockCopy(buffer, 0, totalBuffer, totalBytes, bytesRead);

                    totalBytes += bytesRead;

                    this.Invoke((MethodInvoker)delegate { progressBar2.Value = (int)(totalBytes * 100.0 / contentLength); });

                    if (totalBytes < format.AverageBytesPerSecond) 
                        continue;

                    str = new Mp3FileReader(new MemoryStream(totalBuffer));

                    str.Position = skipTo;

                    while ((decBytes = str.Read(mp3StreamBuffer, 0, mp3StreamBuffer.Length)) > 0) 
                    {
                        provider.AddSamples(mp3StreamBuffer, 0, decBytes);
                    }

                    skipTo = str.Position;

                    if (playingStarted)
                    {
                        playingStarted = false;
                        Task.Factory.StartNew(() =>
                        {
                            
                            play.Init(provider);
                            play.Play();
                        });
                    }
                }
            });

        }

        

        WaveFormat GetWaveFormat(string url)
        {
            HttpWebRequest req = WebRequest.Create(url) as HttpWebRequest;
            HttpWebResponse resp = req.GetResponse() as HttpWebResponse;
            Stream stream = resp.GetResponseStream();
            byte[] buffer = new byte[2048];
            int readBytes = 0, bytesReceived = 0;

            MemoryStream ms = new MemoryStream();

            while ((readBytes = stream.Read(buffer, 0, buffer.Length)) > 0)
            {
                ms.Write(buffer, 0, readBytes);
                bytesReceived += readBytes;
                if (bytesReceived >= 10000) break;
            }
            req.Abort();
            resp.Close(); ms.Position = 0;
            WaveStream tempStream = new Mp3FileReader(ms);
            return tempStream.WaveFormat;
        }
