Copyright is a mess, but more of a mess in some ways than others, and one of the biggest messes right now is licensing music for digital broadcast. The Music Modernization Act aims to smooth over some of the biggest bumps, but a companion piece has aroused the ire of a collection of internet advocacy groups, who have voiced their concerns via a letter penned by copyright scholar Lawrence Lessig.

The CLASSICS Act is the one in question, though no one is disputing the cleverness of its acronym: it stands for Compensating Legacy Artists for their Songs, Service, and Important Contributions to Society. And indeed the goal of the act is to harmonize copyright for musical works created before 1972, a sort of turning point after which copyright law changed considerably.
