The document discusses three cases of copyright infringement in the music industry. The first case discusses how Marvin Gaye's family was awarded $7.3 million after a jury ruled that "Blurred Lines" copied parts of Marvin Gaye's 1977 song "Got to Give It Up". The second case discusses how The Beach Boys song "Surfin' U.S.A." was found to have plagiarized Chuck Berry's song, but the issues were later resolved by signing over writing credits and royalties to Berry. The third case discusses how the famous DJ Avicii made millions from tracks produced using pirated software, though he later obtained legal software after being found out.
