Music in video games usually just sits in the background. It’s texture. It's something that tells your brain "hey, you're in a desert now" or "watch out, a boss is coming." But if you grew up playing Treyarch’s shooters, a Call of Duty song isn't just background noise. It’s a core memory. It’s the sound of 2 AM sessions, empty energy drink cans, and the absolute panic of being cornered on round 30 with an empty Ray Gun.
Honestly, the way these tracks were integrated was genius. You didn't just select them from a menu. You had to find them. You had to interact with weird, out-of-place objects like green meteors or glass jars to trigger the heavy metal payoff.
Elena Siegman and the Birth of the Easter Egg Song
When people talk about a legendary Call of Duty song, they’re almost always talking about the work of Kevin Sherwood and Elena Siegman. Back in World at War, specifically on the map Shi No Numa, we got "Lullaby for a Deadman." It changed everything. Before that, Zombies was just eerie ambient noise and the occasional guttural moan. Suddenly, we had high-octane psych-rock blasting through the speakers.
It wasn't just about the music. It was about the reward.
The community basically turned into digital detectives. You’ve got to remember that in 2008 and 2009, YouTube wasn't the polished machine it is now. We didn't have 4K tutorials uploaded five minutes after a patch. Finding the three meteor pieces on Kino der Toten to hear "115" felt like a genuine achievement. That specific track is probably the most iconic Call of Duty song ever written. It’s got that grinding, industrial opening that perfectly matches the vibe of a dilapidated Nazi theater filled with the undead.
Why "115" Is the Gold Standard
- The Build-up: It starts slow, then kicks into a high-tempo riff that matches the increased speed of zombies in later rounds.
- The Lyrics: Kevin Sherwood writes lyrics that actually tie into the convoluted Aether storyline. "Bring me 115" isn't just a cool line; it refers to the element that reanimates the corpses.
- The Emotional Release: After twenty minutes of silence and stress, hearing Elena Siegman scream "No one can save you!" is incredibly cathartic.
Avenged Sevenfold and the Mainstream Crossover
Treyarch didn't just stick to in-house talent. They leaned hard into the metal scene. If you played Black Ops II, you remember the ending. Seeing M. Shadows and the rest of Avenged Sevenfold performing "Carry On" alongside Woods and Menendez was surreal. It was cheesy. It was weird. It was perfect.
But the real meat was "Not Ready to Die" from the Call of the Dead map. That track actually samples the original Zombies theme. It’s meta. It shows that the band actually played the game. You can tell when a Call of Duty song is phoned in by a corporate studio versus when it's crafted by fans of the franchise. This one was definitely the latter.
They even did "Mad Hatter" for Black Ops 4. While that game had a polarized reception, the song itself is a masterclass in dark, progressive metal that fits the IX map’s gladiatorial aesthetic.
The Sound of Modern Warfare and Beyond
It's not all about Zombies. The main themes of the Modern Warfare series have their own weight. Hans Zimmer—yes, that Hans Zimmer—composed the main theme for the original Modern Warfare 2. You can hear the cinematic scale in every note. It sounds like a billion-dollar blockbuster because, well, it was.
Sarah Schachner's work on the 2019 Modern Warfare reboot took a different turn. It’s darker. It feels more like a thriller. The "Piccadilly" theme is stressful. It’s meant to be. It reflects a shift in the franchise from "action hero" to "the moral gray area of modern conflict."
However, there's a reason people keep going back to the older tracks. The newer games tend to focus on "The Lobby Music." You know the drill. You're sitting there, waiting for a match to start, and there's this repetitive, epic-sounding orchestral swell. It’s fine. But it doesn't have the soul of a hidden Easter egg Call of Duty song.
What Most People Get Wrong About These Tracks
A lot of folks think these songs are just licensed tracks thrown in to sell soundtracks. That's rarely the case with the Zombies stuff. Kevin Sherwood has gone on record explaining that the songs are often written from the perspective of the characters or the "voices" in their heads.

Take "Pareidolia" from Shangri-La. The title refers to the human tendency to see patterns where they don't exist. In the context of the game, it’s about the characters losing their minds. This isn't just "game music." It’s narrative delivery.
The Evolution of the Secret Song
In the early days, the process was simple: find three things, press the action button, and the music plays. As the maps got more complex, so did the triggers.
In Black Ops III, tracks like "Dead Again" or "The Gift" required more than just clicking on rocks. You had to actually engage with the map’s mechanics. It made the music feel like part of the "Grand Easter Egg" rather than just a side treat. Malukah, known for her Skyrim covers, also joined the roster, providing a more melodic, haunting contrast to Elena Siegman’s aggressive vocals. "Where Are We Going?" from Mob of the Dead is a great example of this. It’s somber. It’s sad. It perfectly captures the feeling of being trapped in a hellish version of Alcatraz.
How to Experience These Songs Today
If you're looking to dive back into the best Call of Duty song library, you have a few options that aren't just "look it up on Spotify."
- Zombies Chronicles: This DLC for Black Ops III remastered eight classic maps. The songs are all there, and they sound better than ever.
- The Soundtrack Releases: Kevin Sherwood has released much of the original music across streaming platforms, often under the name "Kevin Sherwood, Elena Siegman."
- In-Game Music Players: Later games like Black Ops Cold War actually included a music player in the menu that let you unlock classic tracks to play during your matches.
Actionable Steps for the Ultimate Audio Experience
To really appreciate the technical work that goes into a Call of Duty song, don't just listen through your TV speakers.
- Check the Mix: These songs are mixed with heavy low-end to compete with the sound of gunfire and explosions. Use a pair of open-back headphones to hear the separation between the synths and the guitars.
- Look for the Instrumentals: If you find the vocals distracting, search for the official instrumental versions. You'll realize how complex the drum programming is, especially on the Black Ops III tracks.
- Trigger Them Manually: If you still have the games, go back and trigger the songs yourself. There is a psychological "hit" that happens when you press the final button and the riff kicks in right as a new round starts.
The era of the hidden Call of Duty song might be changing as the games move toward a more "live service" model with licensed pop music in the store, but the legacy of the original Zombies soundtracks is untouchable. They weren't just songs; they were the heartbeat of the community.

Next time you're loading into a match, take a second to actually listen to the score. Whether it's the orchestral tension of a modern lobby or the hidden heavy metal of a 15-year-old map, that music is doing a lot more heavy lifting for the atmosphere than you probably realize. Stop skipping the intro cinematics and let the audio do its job. You'll find that the game feels a lot more intense when you're actually synced up with the beat.
