Chris Willman Senior Music Writer and Chief Music Critic What might have felt like double jeopardy has turned into a double win for Ed Sheeran, as the pop superstar prevailed in yet a second copyright infringement lawsuit filed over the song “Thinking Out Loud,.” The same judge who oversaw the previous case dismissed this additional suit on Tuesday before it ever got to trial. This like-minded lawsuit had been filed by Structured Asset Sales LLC, another party with an interest in the 1973 Marvin Gaye hit “Let’s Get It On,” similarly contending that Sheeran’s 2014 smash infringed on the previous song’s copyright. The company owns part of songwriter Ed Townsend’s share of the Gaye tune; it was heirs of Townsend who filed the previous unsuccessful lawsuit. The result was much the same, with or without a trial, with the elements shared by the two tunes being judged “common.”
