How do you trigger the BO7 Astra Malorum easter egg song? Treyarch Zombies is now almost synonymous with the music easter eggs you can trigger in each match, with a new and unique track available in each main map.
In Astra Malorum, one of the Black Ops 7 Zombies maps, it's harder than ever to get this easter egg, requiring significant progress through the Astra Malorum main quest. That said, the very special track makes it entirely worth it, so read on to find out more, including all the Astra Malorum Mister Peeks headphones locations you need to find in this Black Ops 7 map.

How to activate the BO7 Astra Malorum song
The Astra Malorum locations of the Mister Peeks headphones are:
- On a shelf inside the Luminarium.
- In a Machina Astralis display case.
- Along the southern wall on Mars.
Luminarium headphones location
First off, you want to collect the headphones just inside the Luminariam, on the bottom shelf of the unit pictured above. You'll need to crouch down to reach and interact with this one.

Machina Astralis headphones location
The second set of Mister Peeks headphones can be found in the Machina Astralis room, sitting inside one of the glass display cases. You don't have to break the glass to interact with the item, but you can certainly try.
Mars headphone location
In an unusual twist, the third and final Mister Peeks headphones location can only be found once you've travelled to Mars, which requires some serious progress through the main quest. Music easter eggs don't usually require this much exploration, so it's harder than ever to reap the auditory rewards of this one.
Once you do reach Mars, you can find the headphones on the southern wall of the space, in the corner to the left of the raised platform. We've not managed to get to Mars, survive, and take a screenshot of the item just yet, but we'll add one when we manage it.
Astra Malorum easter egg track
We're equal parts devastated and elated to say that the Astra Malorum easter egg track isn't by usual Zombies composer, Kevin Sherwood. Devastated that it isn't him, but elated that it is instead by the iconic Avenged Sevenfold.
This absolute banger of a track is called 'Magic', and you can hear it in full above or by triggering the music easter egg in-game. Just don't let it distract you from the task at hand - it takes an unprecedented amount of progress to obtain this easter egg, we'd hate for it to go to waste.
With the Astra Malorum music easter egg checked off your list, and hopefully the main quest too, there are still plenty of other Zombies maps to play, including those in other Zombies modes. You can even find a whole new use for those Gobblegums by playing Dead Ops Arcade 4.
