The theme from Pharos Sirius is definitely my favorite dungeon BGM. Garuda and Titan (in that order) are my favorite boss fight themes. As for my favorite map theme, it would have to be the one for Coerthas (there used to be a vid of it, but it got taken down, grrr).
This is also another favorite (albeit a cover). I remember hearing the melody a LOT back in 1.0 and I never got tired of listening to it. Now, there only a few cutscenes it shows up in... And possibly somewhere in the Black Shroud? Not entirely sure. Regardless, I think it's ridiculously beautiful, despite the simplicity of the arrangement.
