i had problem to run it and i make some changes to run it with mp3 source. here is BackfrounSoundService.java file. consider that my mp3 file is in my sdcard in my phone .

public class BackgroundSoundService extends Service {
    private static final String TAG = null;
    MediaPlayer player;

    public IBinder onBind(Intent arg0) {

        return null;
    }

    @Override
    public void onCreate() {
        super.onCreate();
        Log.d("service", "onCreate");
        player = new MediaPlayer();
        try {
            player.setDataSource(Environment.getExternalStorageDirectory().getAbsolutePath() + "/your file.mp3");
        } catch (IOException e) {
            e.printStackTrace();
        }
        player.setLooping(true); // Set looping
        player.setVolume(100, 100);

    }

    public int onStartCommand(Intent intent, int flags, int startId) {
        Log.d("service", "onStartCommand");
        try {
            player.prepare();
            player.start();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return 1;
    }

    public void onStart(Intent intent, int startId) {
        // TO DO
    }

    public IBinder onUnBind(Intent arg0) {
        // TO DO Auto-generated method
        return null;
    }

    public void onStop() {

    }

    public void onPause() {

    }

    @Override
    public void onDestroy() {
        player.stop();
        player.release();
    }

    @Override
    public void onLowMemory() {

    }
}
