From ancient times to the present day, writers and thinkers have remarked on the unique power of music to evoke emotions, signal identity, and bond or divide entire societies, all without the benefit of literal representation. Even if we can't say precisely what our favorite melody means, we know very well what kind of effect it has on us, and on our friends and neighbors.

According to Aram Sinnreich, this power helps to explain why music has so often been regulated in societies around the globe and throughout history. Institutional authorities ranging from dynastic China's "Office to Harmonize Sounds" to today's copyright collecting societies like BMI and ASCAP leverage the rule of law and the power of the market to make sure that some musical forms and practices are allowed and others are prohibited.

Yet, despite the efforts of these powerful regulators, musical cultures consistently devise new and innovative ways to work around institutional regulations. These workarounds often generate new styles and traditions in turn, with effects far beyond the cultural sphere.

Mashed Up chronicles the rise of "configurability," an emerging musical and cultural moment rooted in today's global, networked communications infrastructure. Based on interviews with dozens of prominent DJs, attorneys, and music industry executives, the book argues that today's battles over sampling, file sharing, and the marketability of new styles such as "mash-ups" and "techno" presage social change on a far broader scale.

Specifically, the book suggests the emergence of a new ethic of configurable collectivism; an economic reunion of labor; a renegotiation of the line between public and private; a shift from linear to recursive logic; and a new "DJ consciousness," in which the margins are becoming the new mainstream. Whether these changes are sudden or gradual, violent or peaceful, will depend on whether we heed the lessons of configurability, or continue to police and punish the growing ranks of the mashed up.

Any and all songs are capable of being remixed. But not all remixes are treated equally. Rock This Way examines transformative musical works—cover songs, remixes, mash-ups, parodies, and soundalike songs—to discover what contemporary American culture sees as legitimate when it comes to making music that builds upon other songs. Through examples of how popular discussion talked about such songs between 2009 and 2018, Mel Stanfill uses a combination of discourse analysis and digital humanities methods to interrogate our broader understanding of transformative works and where they converge at the legal, economic, and cultural ownership levels. 

Rock This Way provides a new way of thinking about what it means to re-create and borrow music, how the racial identity of both the reusing artist and the reused artist matters, and the ways in which the law polices artists and their works. Ultimately, Stanfill demonstrates that the extent to which a work is seen as having new expression or meaning is contingent upon notions of creativity, legitimacy, and law, all of which are shaped by white supremacy.
