Music during combat = you can't hear when someone is jumping near you or where the action is at. So I really don't have a preference, since It's turned off for me personally. That being said, datamine is all about hostility and danger, so it would be appropriate.
Wow, I forgot MxO had music
I have it all on iTunes though so ^_^
I usually have the music off too but I do turn it on now and then! It helps to get you in the Matrix mood!
I love the loading area music and international district music when you are outside, but not so much the other districts
Oh and the Merv music fits perfectly with the Merv organization I think! :)
Yeah, I normally leave my game music off due to vent/music but if ever you feel like getting into the Matrix mood the music is great for that.
I like the Richland music, sets the right atmosphere for the slums
Procurator-
The datamine music is the same as the music you here when you go inside a building Downtown, and maybe in Westview also.
Personally, I don't really listen to any music in game most times, just to help reduce m,y lag a little. But i actually like the music choice in DM. It strikes me as kind of quietly tense, which is how DM is most of the time these days. Like there is noone around, but you might get jacked at any minute. Anyway just my two sense.
