Simple question, what songs do you like to play when you are off venturing around the desert?
For me, it's House of the Rising Sun by The Animals, for some reason I find that song very fitting and relaxing when you're travelling across the Mojave!

Also, if you want, list songs you liked to listen to whilst playing Fallout 3, I always listened to Tears don't fall by Bullet For My Valentine, suitable music for wiping out raiders!
