Yeah, BG3's music was my biggest disappointment with the game.
After DOS2, where even after dozens of playthroughs, I still stop in awe of the excellent soundtracks and just listen. BG3 music tends to feel rather repetitive and less memorable outside the one song...
Which it's not a bad song. It was nice when in the character creator. But then after? When it kept reappearing throughout the game? When music boxes would play the same song? It started to feel a little bit overdone...
Like even if it's supposed to be linked to the story... It's better to bring it out to emphasise its link to the story, not just toss it everywhere all willy nilly.
I think it was initially tied to their central plot. There’s a thread somewhere on these forums, titled Daisy, the absolute, and the Emperor, I believe? You can probably find more info on it there.
