Looking through the forum I didn't see any topics dedicated to players' fave tracks, so here's one.
What are your favourite tracks in DD?
Mines are:
Golden Sacks - the atmosphere gives a good feeling of adventure and some parts remind me of great memories playing HoMM 3
Whaaarrgarrrbl - very intense song. Whenever I hear it it makes me feel like a berserker


Boggy Bottom - a nice calmer, more ambient music, reminds me of Bastion at parts
Dunes of Damnation - same story as with Whaaarrgarrrbl, but with a wizard feeling instead of warrior
Also all the vicious levels have some epic music, and the music change when you go from one part to another is a great touch. My absolute fave is Namtar's music. When listening to that you know you're not dealing with your everyday boss.
