I often listen to an awesome small band called The Phenomenauts. Absolutely all of their songs are about science-fiction, robots, space travel history, and humanity\'s exploration. It\'s mostly in the odd genre-mash of old school rock-a-billy, mixed with punk and doo-wop. Haha, I know how odd that must sound, but trust me, it is PERFECT for KSP. Search for them on GrooveShark or something similar. Some of my favorite songs are 'Where is the X-38?', 'The Colvin Moon', 'The Tale of Europa', 'Rocket Roll', 'Make a Circuit with Me' and 'Composite Synthesizer'.
