“Call it Antonoffication: the process of the dispersion of the aesthetics of indie rock out from a distinct subcultural enclave and into a general ether that suffuses and unites the major genres of today’s Top 40 pop music. Which is to say, the complex process of cultural mediation through which all pop music today has become a little bit indie rock. In the 2000s, a fierce debate raged among music critics between proponents of “rockism,” those committed to enclave principles of taste and a rigorously policed standard of authenticity, and of “poptimism,” those who resisted the idea that some musical genres were worthy of serious critical attention and others were not. Today such terms, along with the divide between high and low culture on which they were premised, feel almost foreign. Increasingly, where once there were musical subcultures with their own standards of taste, under the regime of streaming there is now a free-floating tastefulness, a pop version of what Lee Konstantinou calls “mass high culture.””
