South Korean children's education entertainment brand, Pinkfong's "Baby Shark" is an undeniable global phenomenon.
The company's flagship video series has millions upon millions of views, while making a surprise landing to the Billboard Hot 100 song chart.
However, American children's music performer Johnny Only filed a complaint with the Seoul Central District Court in October, 2018 against Smartstudy, the parent company of Pinkfong, with the first hearing taking place last year.
He is demanding over four-thousand U.S. dollars as compensation for plagiarizing his song.
Do they really sound similar?
Johnny Only says Pinkfong's "Baby Shark" is brighter than the original campfire song, but insists the composition of the musical instruments is also very similar with his song.
"Compared to the original song, the music has a clearer melody and beat. It also has an additional harmony. This is all evidence of plagiarism."
Smartstudy dismisses Only's claims, saying "Baby Shark" is based on a traditional singalong chant which has passed to public domain.
It adds the song was adopted, rearranged and the lyrics were changed from the original version.
The Korea Copyright Commission is now set to review both songs before the case can proceed further.
Now, all that's left to be see is who truly owns the song that got the whole world whistling along to its catchy hook.
