A copyright battle over the viral song “Baby Shark,” adored by young children and often dreaded by their parents, has come to an end with a court clearing the Korean creators of the most popular version of plagiarism.

South Korea’s Supreme Court has rejected a 30 million won damage claim by an American composer who accused a South Korean kids content company of plagiarizing his version of “Baby Shark.”

The judges found “Baby Shark” was based on a nursery rhyme, dismissing the six-year case of U.S. entertainer Johnny Only that centered on his 2011 version.
