BARRIO (Billboard) – Karol G and Tiësto are facing a copyright infringement lawsuit over their song “Don’t Be Shy,” filed by a Cuban-American songwriter who says their track features elements that are “practically identical” to his earlier tune.

In a complaint filed Tuesday in Puerto Rico federal court, lawyers for songwriter Rene Lorente claim that Karol G and Tiësto’s 2021 dance-pop hit infringed his 2000 song “Algo Diferente” by using a melody that “sounds identical.”

“It doesn’t take an expert or musician, to carefully listen to the melody/sounds of each, to recognize that one was copied from the other,” Lorente’s lawyers wrote in their complaint. “In this case, defendants’ ‘Don’t be Shy’ is a blatant violation of plaintiff’s copyrighted ‘Algo Diferente’.”

Karol G, who is currently sitting atop Billboard’s Hot Latin Songs chart with her “Qlona,” teamed up with Tiësto to release “Don’t Be Shy” in August 2021. The song, which hit No. 4 on the Hot Dance/Electronic Songs chart, was the Columbian star’s first released in English.

But in his lawsuit, Lorente claims Karol G and Tiësto’s song “misappropriated his beloved copyrighted work” – a tune released in May 2000 that currently has 3,647 total streams on Spotify. A version of “Algo Diferente” on YouTube, uploaded just nine days ago by CD Baby, has been streamed 6,423 times.

According to Lorente’s lawyers, a comparison of the two songs shows that they are “substantially similar” – the requirement to prove copyright infringement.

“Expert analysis of musical arrangement fragment of the copyrighted and infringing works, show exact rhythm, note arrangement, same intervals, harmony, with the only change being limited perhaps to the pitch, within 8 musical bars, repeated throughout infringing work,” Lorente’s lawyers wrote in his lawsuit. “However, for a lay listener and a jury, this combination of musical notes sounds identical.”

The lawsuit is seeking a whopping $52 million dollars, but attorneys who file lawsuits can claim any damages total they want. Even if Lorente’s lawsuit was successful – and that is not a given – such demands are typically not good indicators for what a judge or jury might ultimately award.
