I have slowed the tracks down a little bit for note learning purposes. It should be faster in performance (see videos below). Don't forget that there is a pronunciation guide on the inside cover of the score. It is very helpful. And definitively states that it is pronounced "Jayzoo."
To play the track, just click on the line you want to listen to. You can fast forward and rewind through the track by dragging the little moving line. To pause playback, click on the pause sign on the album cover.
