so ill keep this short because there is no other good way of putting this but, on the black ops 2 zombies map "Mob of The Dead" all the perk jingles used are shortened down for a more spooky effect which is unique to the map but unfortunately that leaves the perk introduced in the map Electric cherry without a proper jingle and just a shortened spooky version of it. However it is relatively commonly known that most of the jingles used are stock music loops that have added lyrics so there is an on going search to find electric cherrys original jingle.
(more info about this jingle) its theorized that the jingle is a sort of 80s or 70s disco styled jingle and other than that thats all we have this was stated by a dev in an interview circa 2015ish and I believe it was a rafflewaffles video that people get this info from
