The music in Generals was done by Bill Brown. He's better known for composing the Rainbox Six series of games including the main theme and he has a very Hans Zimmer like style to him. Basically thats what they wanted in C&C Generals and thats what he gave them and its a very good soundtrack, I'm sorry if it doesn't go along with what some of you thought it should be, but I was very impressed with the quality of the Generals soundtrack. It was done to sound like a serious thriller movie and thats what it is. Generals is part of the C&C franchise but it was well established with Red Alert that the C&C name was about the style of gameplay and not specifically the story in question.
Generals was a natural evolution...I expect C&C3 will be somewhat similar to Generals in many ways. Tiberian Sun dropped the ball while RA2, RA, and the original C&C was what the gameplay style was all about.
