In 1997, German rapper and hip-hop music producer Moses Pelham copied a two-second sequence from the pioneering electronic band Kraftwerk's 1977 track "Metall auf Metall" (Metal on Metal) without permission and placed it in an endless loop in the song "Nur mir" by rapper Sabrina Setlur.

Ralf Huetter and Florian Schneider-Esleben, founding members of Kraftwerk, sued Pelman, citing infringement.

"Sampling" is a technique that extracts bits of another work, such as a rhythmic sequence, and incorporates them into a new composition.

Copying and applying such excerpts interferes with the rights of the producer and, without permission, constitutes infringement, said Maciej Szpunar, an advocate general of the European Court of Justice (ECJ), on Wednesday.

Striking a balance

First going through the rounds of German courts, in 2016, Germany's Federal Court of Justice referred the lawsuit to the ECJ.

Szpunar's conclusion that copyright holders must grant approval for sampling is in line with the European Union's fundamental rights, even though copyright and related rights "are likely to restrict the exercise of certain fundamental rights, in particular, the freedom of expression and the freedom of the arts," he said in a press release.

"Intellectual property is itself protected as a fundamental right to property," he pointed out. "It is therefore necessary to strike a balance between those rights."

An advocate general's opinion is not binding for ECJ judges, but they often adhere to it. A verdict is likely in the coming months.
