I noticed that even if you have "continuous music" button unchecked, as soon as you enter a randomly generated structure, ( so far for me in meadows only) it starts that new music, and when you leave it, it force starts the regular meadows continuous music as well, (button is still unchecked) and forces music to stay on, as well as overlapping like crazy during transition. Have had success fixing this only by restarting game AWAY from a randomly generated structure and not bothering to go near them for the most part. Then, creepily, it sometimes starts again randomly when I'm not near a structure. Definitely a bug.
