Back in the heyday of DOW1, I used to mute the music, fire up the ol' winamp and put on my personal soundtrack. It was mostly Castlevania covers by this guy named GOAT. http://ocremix.org/artist/4512/goat/remixes The gothic metal was a perfect fit because nothing is as gothic or metal as 40k.
You guys ever do this? What were your personal soundtracks?
