I'm assuming you're not talking about the intentional pads in the soundtrack, I haven't seen this issue but it's possible there is something there. As I understand, Godot's dynamic audio stream is quite new so perhaps it has some bugs or I might've set it up incorrectly. I was planning to include a sound slider to turn down the music, but I couldn't get to it within my time constraints.
If anybody else gets these kinds of issues, I'd suggest muting the tab: you're not missing much other than the track I made
