I love listening to @ Minutes to Midnight by Iron Maiden or Burning Birdges by the Mike Street Congregation (I forget their name, so thats probably wrong) a little when i play DOD. I dont do it a lot, because I have to rely on sound to listen for footsteps, etc. And since VAC is so fucked up, you have any other porograms running when you enter a VAC secure server, it automatically bans you from EVERY SINGLE SERVER for 4 YEARS

It happened to my friend who ran Winamp minimized and VAC detected it as a cheat, so banzor for 4 years.
