Of course, there's an album that he buys three times because he wants to have it on every format ... Which brings it back to materialism.

Fro me, the music chapters show how he has to over-analyse everything, deconstruct it and take it apart instead of just enjoying it. Look at the praise he dumps on Huey Lewis and the News ... All those superlatives! Is that a fair, honest, appropriate assessment?

(Aware of the irony of over-analysing the music chapters after what I've just written!)

Edit: They also give us the scene in the filmed version where he monologues about Genesis (?). Pure brilliance!
