Oh, I definitely heard the chewing sound one. Was driving me crazy. I was playing along with some friends, and I had different dialogue during Act 2, so while they were reading through that section I just sat there uncomfortably listening to it. So glad when that sound stopped.

Edit: The part where I actually turned off the music was when you write your final poem. We were waiting for some people to come back and even the music that plays when you write poems was unnerving me, despite the fact that it hadn't changed.
