NotifyIcon isn't showing BalloonTip in play button event C#

.NET4.5

I'm working in a music player, I want a NotifyIcon to show a balloonTip displaying the title of the current song.

I have the play button, which will make the player start sounding a mp3 file, in the same button event, I placed my notifyIcon balloonTip set. But it isn't showing and I have been looking for errors on Debugging Mode but it did not popup anything else.

My code:

private void playBtn_Click(object sender, EventArgs e) //Play Button
    {
      player.URL = @"C:/myFile.mp3";
      notifyIcon2.BalloonTipText = player.currentMedia.getItemInfo("Title") + " - " + player.currentMedia.getItemInfo("Artist");
      notifyIcon2.ShowBalloonTip(1000);

NOTE: The player is working, what isn't working is the notifyIcon balloonTip.

Please help me. Thanks in Advance - CCB
