Can you copyright a rhythm? Inside the reggaeton lawsuit that could shake the pop world

Two dembow progenitors are suing superstars including Luis Fonsi and Daddy Yankee - in a case that also names Justin Bieber - claiming that they deserve credit for birthing the genre

With the release of their song Fish Market in 1989, the Jamaican duo Cleveland Clevie" Browne and Wycliffe Steely" Johnson inadvertently changed the course of pop music. The track featured the first known example of what would come to be known as a dembow" rhythm - the percussive, slightly syncopated four-to-the-floor beat that travelled from reggae to become the signature beat of reggaeton, today the world-conquering sound of Latin American pop.

Now, more than 30 years after Fish Market was released, Steely & Clevie Productions is suing three of reggaeton's most celebrated hitmakers - El Chombo, Luis Fonsi and Daddy Yankee - for what they characterise as unlawful interpolation of Fish Market's rhythm (or riddim"), and are seeking the credit - and royalties - they say they deserved from the start.
