February 23rd, 2012. Electronic violinist Lindsey Stirling uploads the official music video for "Crystallize" to YouTube. Two days later, user "riley lux" uploads a video titled "DH long boarding on a windy day." In it, a group of friends enjoy some downhill riding set to Stirling's haunting violin-based soundtrack. The video itself isn't remarkable. Some self-shot GoPro footage, with a few edits roughly in time with parts of the song. But, there's something about each pass of Stirling's bow that balances the on-screen energy with a tangible calm. Later the same day, user "Jvr0s" chooses the same song for a video called "GPK Fun around town." In it, a group of friends practice parkour. This video is entirely forgettable, but for the song -- it somehow manages to elevate the otherwise unremarkable action cam footage.
My first exposure to the track is also on an action sport video, during a wingsuit video marathon, to be precise. Long after my first encounter, I hear the song again on an F-18 pilot's GoPro video; remembering it, I use Shazam to find out what it's called. I scour my YouTube history and realize: This song has been following me for months through its popularity on YouTube GoPro videos and I've only just noticed.
The question is: Why am I hearing this song in videos more than... well, any other? Is it a free download on some action sports site? Was it used in an advert for GoPro? Maybe it's just confirmation bias? Or, perhaps, Stirling's stumbled on a secret formula. Something in the song's DNA that makes it particularly suitable for soundtracking sweet jumps, aerial rides, hula-hooping, surfing, wingsuit flying or, seemingly any and every form of action-based activity?
As of this writing, searching YouTube for "Crystallize GoPro" returns about 12,000 results. By contrast, searching for "Rihanna Diamonds GoPro" (an arbitrarily chosen popular song), you actually get about 10,000 more results. However, scroll down and you'll soon see that the action videos using Rihanna's song are few, and drop off almost immediately. YouTube fills the space with "Results for similar searches." You can go 10 pages deep after searching "Crystallize GoPro," and still find more action videos soundtracked by the song. When I first noticed this, it seemed like an in-joke I didn't know about. Some videos are perhaps less suited for the piece, sure; it's not a panacea. But most -- the clear majority -- are improved by it.
