I was doing some research and found out that all of the perk jingles otherthan a few from ColdWar, and Vulture Aid, are acutally just ripped from songs that alreadt existed, which I thought was interesting as we see these jingles as iconic, but all of them had been around for a long time before zombies! While Treyarch did add the lyrics and change the melody a bit, I thought I would try to honor the artists that brought us the original songs.
