Electric Worry by Clutchyoutube it, i think its wrote just for left 4 dead 2
The song from the Left 4 Dead 2 TV Spot is "Electric Worry" by "Clutch". I'm assuming the lyrics you heard were: "Bang, bang, bang, bang! Vamanos, vamanos! Bang, bang, bang! Vamanos, vamanos!" Don't worry, the rest of the song has other lyrics, not just those repeated words.
