I LOVE the music in BG3. It has a Beats Antique vibe to it. Its much richer, deeper and more complex than the music from the previous games. I love "Down by the River" and pretty much haven't heard anything I didn't think was a masterpiece. The music sounds orchestral as well, with a wider range of instruments used.
My hope is we hear more music like this.
As for the BG1-2 music. It was ok. It feels a little flat to my ears compared to the BG3 music but I think a lot of that was the limits of the medium and it sounds like it was mostly produced on a synth. Its not bad at all, but its also highly repetitive, doesn't take any real risks or make any complex statements. I think if you enjoy Nickelback - as I assume most of you complaining surely do - then I am sure it sounds brilliant to you. :P
I swear most of you must wrack your brains all day to find stuff to complain about. How is that not exhausting?
