This podcast episode explores the complexities of music copyright infringement cases and the role of forensic musicologists in determining whether a song is an inspiration or a theft. The episode discusses the Arnstein test, a two-part framework used in music copyright infringement cases, which helps evaluate whether similarities between two songs are a coincidence or evidence of copying. Through examples of cases like Ed Sheeran's "Thinking Out Loud" and Marvin Gaye's "Got to Give It Up," the episode highlights the subjective nature of these cases and the potential impact on the music industry and the protection of musical creativity.
