Streaming rights are at the center of a lawsuit filed against Universal Music Group by pop star Enrique Iglesias, the AP reports.

“The lawsuit filed in Miami federal court claims that Universal is paying Iglesias far less than the 50 percent royalty rate required under his contract for streamed music,” the story reports. “Iglesias says Universal is paying him a lower rate based on sales of physical music such as compact discs even though there are far fewer overhead costs.”

The 42-year-old Iglesias lives in Miami Beach with his longtime girlfriend, tennis star Anna Kournikova, and their newborn twins, the report notes. He has sold almost 160 albums worldwide.

Attorney James Sammataro, who represents Iglesias, said in an email: “Artists, producers and songwriters should benefit from the reduced costs of streaming, not have their musical works spin unwarranted profits. Universal has long ignored, and is now attempting to distort, the clear terms of its artist agreements so that it alone reaps the savings from digital streams.”
