The addictive children’s melody Baby Shark has become the most-watched video on YouTube, with its upbeat and catchy lyrics reaching over 7 billion views.
The most recent version of the song recorded by South Korean company Pinkfong has won the hearts of kids, and even some adults, with a melody that will linger in your head long after you have watched the video.
Parents might tell you a different story, however, as they struggle to get the darn tune out of their heads after their obsessed kids have hit replay too many times.
The song has an interesting history – here's what we know.
In 2019, Pinkfong was sued by children's songwriter Jonathan Wright, who in 2011 recorded a similar version of the song and argued he owned the copyright to that interpretation.
Pinkfongs's mother company, SmartStudy responded by saying their version was "based on a traditional sing-along chant which has passed to public domain". There is no record of the outcome of that lawsuit.
There are many international versions of the song, including the French Bebe Requin and the German Kleiner Hai (Baby Shark) that became a minor hit in Europe in 2007.
However, it is the latest version of the song that was recorded by 10-year-old Korean American Hope Sengoine in 2015 that has made it the internet sensation it is today.
According to BBC news, the song has been played 7.04 billion times making it the most watched YouTube ever, even surpassing Lius Fonsi’s Despacito featuring Daddy Yanke with 7.03 billion views.
Although there is no confirmed official source, it's believed the song may have originated in US summer camps in the 1970s.
There's also a theory it was invented in 1975, as Steven Spielberg's film Jaws became a box-office smash around the world at the time.
In the latest video, Baby Shark Dance features two adorable children with goofy dance moves, which is what seems to be setting it apart from the other versions. The repetitive “dooo doo doo doo doo doo” melody makes the song hard easy to love - for the kids at least.
But beware – there's another, decidedly less innocent side to such tunes.
In October, it was reported the song had been used by Oklahoman officers to torture four inmates by forcefully making them listen to the song for hours.
According to health.com, two former employees at the Oklahoma County jail together with their supervisor were charged with misdemeanor counts of cruelty to a prisoner and conspiracy after forcing inmates to listen to Baby Shark repeatedly “at loud volumes for extended periods of time”. Investigators found the employees forced at least four inmates to stand, secured to a wall and with their hands cuffed behind them, for hours and listen to the song. It was said that listening to catchy songs can evoke a pain response from the brain.
