I'm a composer, and I will say some of the main themes are pretty good but the 'down by the river' theme is re-worked and brought back in way too many ways.
It's a common trick and a nice one when employed gracefully but it's almost like he couldn't come up with another strong melody.
Overall though the orchestral music is pretty great in the game except there are SO many music choices that completely take me out of it.
Pretty much anything with those female vocals in this game just sound like early 2000s pop/emo rock stylings and NOT old at all.
It's like the difference between the Witcher game (good) vs Witcher tv show music (baaaaad).
I can't stand the camp music once you're in the fancy Baldurs Gate camp with the 'the games not over yet' on the nose cheese lyrics and I have a love/hate relationship with the house of hope Raphael battle song with lyrics.
I wouldn't call the music in this game a masterpiece, but I think he did a 'good' job.
