Battlefield Vietnam, i loved the music feature, playing songs like "You really Got Me Now," while flying into the enemy base in a jeep. Or "Ride of the Valkyries" In a Huey Gunship when you're about to capture the last enemy base, or playin "Fortunate Son" by CCR in Irving or Ia Drang (SP?) while flying a Huey Slick full of men into enemy territory, then it really feels like a Vietnam movie. Good times...good times...I loved that game, when i got BF2 i missed the music feature, so i played music from my Windows Media Player playlist. Hair metal is great for the intense action of Karkand. Unfortunately its even better for sneaky enemies...so if have to keep it quieter when online, or turn it off completely.
wow i should stop before i get too far off subject...anyway like someone else said (was it LadyM?) the first thing that popped into my head was the song titled "War" another one from BFV.

(edit- just thought of this, is Edwin Starr related to Ringo Starr of the Beatles?)
