D. Ascendant -- I totally agree!!!!!
The whiny, faux Chinese/Oriental music is enough to drive any person insane. However, if it was that rythmic drum music that pops up when you are asked whether you want to load a game, start a new game, etc., I could go for that.
In short, I'm like most of the respondents -- provide my own music. Being older, I go for Pink Floyd - Dark Side of the Moon or Wish You Were Hear -- some good old Blue Oyster Cult or Led Zepplin. Phish is good as well, and Metallica seems to fit the pre-A.D. years. Offspring, maybe, but that's about it.
In a related issue, how about the game sounds? Much has been made of my fondness for the Elephant unit's trumpeting, but really, after a while, I just mute the whole damn thing, rock out and rock on.
