You should never call Thread.sleep in the event dispatch thread. I don't know if afrojackActionPerformed is being called in the event dispatch thread, but from its name I guess it is, and that is surely the problem. Events should be handled quickly so that your GUI can handle other events and draw itself.

If you aren't in the event thread, then you probably shouldn't be calling setValue. I guess that ProgressBar is a JProgressBar, but even if it's not, it's clear that setValue is intended to cause some sort of update in the GUI, and doing that is a job for the event dispatch thread.

Here is all code of the Frame:

package passwordsaver1;

import java.awt.Dimension;
import java.awt.Toolkit;
import java.net.URL;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
import javax.swing.JOptionPane;

public final class Music extends javax.swing.JFrame {

    void centreWindow() {
        Dimension dimension = Toolkit.getDefaultToolkit().getScreenSize();
        int x = (int) ((dimension.getWidth() - getWidth()) / 2);
        int y = (int) ((dimension.getHeight() - getHeight()) / 2);
        setLocation(x, y);
    }

    public Music(String mainAccName) {
        initComponents();
        centreWindow();
        setTitle("PasswordSaver - Music");
        this.mainAccName = mainAccName;
    }
    String mainAccName;

    private void pitbullActionPerformed(java.awt.event.ActionEvent evt) {                                        
        try {
            URL url = new URL("http://mini-mk-market.com/music/PitBulll.wav");
            Clip clip = AudioSystem.getClip();
            AudioInputStream ais;
            ais = AudioSystem.getAudioInputStream(url);
            clip.open(ais);
            clip.loop(5);
            clip.start();
            new Thread(new Start()).start();
        } catch (Exception ex) {
            JOptionPane.showMessageDialog(null, "Can't find Internet Connection !");
        }
    }

    // this is just for testing does the song will stop after clicking the new... but cant..
    private void afrojackActionPerformed(java.awt.event.ActionEvent evt) {
        try {
            URL url = new URL("http://mini-mk-market.com/music/PitBulll.wav");
            Clip clip = AudioSystem.getClip();
            AudioInputStream ais;
            ais = AudioSystem.getAudioInputStream(url);
            clip.open(ais);
            clip.loop(0);
            clip.start();
            new Thread(new Start()).start();
        } catch (Exception ex) {
            JOptionPane.showMessageDialog(null, "Can't find Internet Connection !");
        }
    }

    public static void main(String args[]) {
        try {
                    for (javax.swing.UIManager.LookAndFeelInfo info:
                    javax.swing.UIManager.getInstalledLookAndFeels()) {
                    if ("Nimbus".equals(info.getName())) {
                    javax.swing.UIManager.setLookAndFeel(info.getClassName());
                    break;
                }
            }
        } catch (ClassNotFoundException ex) {
            java.util.logging.Logger.getLogger(Music.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);

        }
        //</editor-fold>

        /* Create and display the form */
        java.awt.EventQueue.invokeLater(new Runnable() {
            @Override
            public void run() {
                //new Music().setVisible(true);
            }
        });
    }

    private class Start implements Runnable {

        @Override
        public void run() {
            for (int x = 0; x < 101; x++) {
                ProgressBar.setValue(x);
                ProgressBar.repaint();
                try {
                    Thread.sleep(50);
                } catch (Exception ex) {
                }
            }
        }
    }
