Very atmospheric music, bad value

The CD Les Choristes is really great. The songs develop as atmospheric effect as the corresponding film, even though the images are missing. Two downer there, however: 1. While there are 21 tracks on the CD, but they are all very short, on average, maybe a little over one and a half minutes. 2. The melodies are repeated constantly. So you have not even 21 different tunes on the CD, as many pieces which, although different hot, have the same tune, is practically to the same song.
Accordingly, the value for money is not great shakes.
