Biggest problem with this documentary is the lack of music even thou the documentary is about music.

Everytime a new composer is brought along and started talking about what music he made or something about how music changed from one way into another they did not play a single soundtrack.

If someone says "this song changed everything with how the channels where mixed and so on and so on" Would have been real easy to just play that song and make an example on how it changed from how it was done before.

Now it just felt so empty cause you could not really fully understand what changed in the music.
