Personally, I never look for good music in video games. If it's good and fits well, it's a bonus, if not then I don't care and turn it off if it becomes annoying. The music in BG3 is nothing special and forgettable but I don't mind it being like that.
The games, which I remember for exceptionally good music score: The Witcher and The Witcher 3, Stellaris, Mongolian theme from Crusader Kings 2, Star Control 2, Vampire the Masquerade: Bloodlines club music. That's it.
