To be fair, Metallica isn't for everyone.
Dee Gallant, 45, was enjoying an ordinary day when she was hiking with her dog, Murphy, near South Duncan, a small town located on British Columbia's Vancouver Island.
However, what started as a peaceful stroll quickly turned into a heart-pounding standoff when she locked eyes with a predatory cougar.
As you're about to see, this Canadian woman gets the cougar to stop in its tracks, but she was not able to get it to retreat.
Watch the video below:
While you won't see it in this video, Gallant fortunately had a trick up her sleeve that would ultimately protect her, echoing irony throughout the woods.
She reached for her phone and played "Don't Tread on Me" by Metallica, a tune that's perhaps never had such a fitting application. It seems the cougar disliked not only the loud nature of Metallica's music, but also the lyrics that symbolized one holding his or her ground.
The hiker likely had to stop recording in order to access her music library, but it's a bummer we couldn't see footage of that!
"I actually thought it was really cool that I got to see a cougar for so long," she said. "I thought it was exciting."
She said she left Metallica song playing on repeat for the remainder of the hike, too, just in case the cougar decided to circle back.
"I definitely think Metallica saved the day there for sure," she said.
