I was doing some research and found out that all of the perk jingles other than a few from Cold War, Vulture Aid, and Widows, are actually just ripped from songs that already existed, which I thought was interesting as 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. So some of the jingles are HELLA long but I don't care. I think it is a part of zombies history, and I decided to honor the original instrumental tracks!
