I am one that is against the idea of changing the volume. Its great dynamic range is part of what makes the visceral impact work at it's climaxes. I heard the score with the normalization on in Spotify once. And I immediately I noticed the bass was all distorted. What may help those who claim the music inaudible perhaps need a better amp in their systems. Its a really good recording and time shouldn't be wasted playing it on some cheap-ass boombox.
On a tear lately...so here is my analysis of James Newton Howard's superbly understated "Unbreakable" score. The first time I heard it, it seemed a bit nondescript, but after a few listens the themes really snuck up on me (not just the Vision theme, that is, that one I loved from bar 1). Really nice stuff and it doesn't hurt that it's by far my fav MNS film.
