Mark Goldstein, Clinical Professor of Music Industry at USC’s Thornton School and former VP of Business Affairs at Warner Bros. Records, discusses some legal aspects of today’s music industry, and what the future holds for musicians and the music they make. In specific, he discusses the current vogue for “360 deals” and whether they have any future merit for artists or record companies, the current legal status of file sharing and sampling and how to avoid giving all your royalties away to someone else, and the real main source of most artists’ income (hint: it’s not album sales).
