Ed Sheeran Defends Himself in Copyright Infringement Trial.

Ed Sheeran testified in a copyright trial in which he is accused of copying Marvin Gaye's "Let's Get It On" for his song "Thinking Out Loud." Sheeran said he and co-writer Amy Wadge created the song independently, inspired by his grandparents. The plaintiffs argue that the "heart" of "Let's Get It On" was copied by Sheeran. Sheeran's lawyers argue that the elements are basic musical building blocks in the public domain. The trial continues.
