Katy Perry sold the rights to most of her music for a cool US$225 million last month to Litmus Music. It’s the latest in a series of high-profile payouts. Tempted by eye-popping offers from investment firms like Hipgnosis and Shamrock Capital, Paul Simon, Dr Dre and other artists have sold out — literally.

These deals are the consummation of a revolution that began over a century ago when music copyright first began its improbable metamorphosis from a limited legal claim to something that can be monetized on a mass scale.
