Near the bottom it says they added "discovery music" for the Black Forest. It triggers near any generated structures, like Burial Chambers and dilapidated buildings. Unfortunately, it's programed as a very simple proximity trigger; whenever you get within range, it will play. This can be quite annoying for players that like to squat in stone ruins (like myself) because it will trigger constantly and completely drown-out all other music.

Here's hoping the devs add a simple "discovered" flag in the code that disables repeat triggers in the future. I can't play with the music going anymore. :(
