Are there any extra prerequisites for the Master Trophy Collector "Trophy." I'm sitting at 49/50 and haven't been awarded it, even when starting a new game.
There is a music / SFX decrease nob in the lower right corner at the menu screen, REALLY easy to miss. (Just a tip for people like me, although it'd be nice to mute the music entirely)
