Try it this way....

public class Blah extends Activity implements OnClickListener {
   MediaPlayer mp;

   @Override 
   public void onCreate(Bundle b)
   {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.main);

      Button e = (Button) findViewById(R.id.Button1);

      mp = MediaPlayer.create(R.raw.match);
      mp.setOnCompletionListener(new OnCompletionListener() {

        public void onCompletion(MediaPlayer mp) {
            i.release();                    
        }
    });

      e.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {

                   mp.seekTo(0);
                       mp.start();

            }
        });
   }
