Lee,
I do like the examples you gave of your own game.
A great soundtrack is the soundtrack for the movie "Sorceror" by Tangerine Dream, a great synthesizer-driven sound! Despite the name and the trippy title, it's really about a bunch of guys driving a truck full of nitro to put out a oil-well fire at a wellhead over rough South American roads.
