Ed Sheeran has appeared in court in New York accused of copying part of Marvin Gaye's track "Let's Get It On".
The singer-songwriter denies using elements for his 2014 song "Thinking Out Loud".
He's being sued by the family of Ed Townsend, who co-wrote the 1973 hit.
His lawyers argue the two songs are distinct, and that 'no one owns basic musical building blocks'.
The trial is expected to last about a week.
