Could be. But just because he's interpreted the song wrong doesn't mean he can't have genuine feelings towards it.

I dunno. I just love talkin about books.

This is true.

Maybe you're on to something about the "genuine" of music in a world of materialism.

Did you read the same book? It's not sonatas. It's pop. Are you thinking of Alex in A Clockwork Orange?

Maybe the music chapters are little reminders that the shell/facade of a man still feels?

I personally just took it as an extension of his obsession with the way he is perceived by others. Music is one thing he can invest in that adds to the facade he's cultivating. Not to mention the artists he talks about are all famous at the time so maybe it's just him mirroring the rest of the USA's infatuation with celebrities.
