Anyone who went straight to YouTube to look for Prince’s music following his death was in for a surprise. There is one outstanding concert from 1982, a short NFL film on his epic Super Bowl halftime performance, and, well, not much else. As the creator of all his own music, Prince valued it tremendously and starting in 2007 he made it his goal to end unauthorized use of it. Ownership was another challenge. His initial deal with Warner Bros. gave him the publishing, but not the masters—which eventually led him to appear with 'SLAVE' written across his face. He was still referring to record contracts as “slavery” as recently as last year even though he re-signed with Warner Bros. and received the rights to his ‘80s masters in 2014.
