The name of PWEI was stolen from an article in the NME written by David Quantick about a band named Jamie Wednesday. The phrase was used to discuss how pop music utilizes only the most successful (selling) music as its foundations, so eventually pop music becomes built on no musical tradition more far-reaching than a base of that pop music which preceeded it, of the best-sellers of all time.

Often misinterpreted by smart young folk, however, to refer to sampling.
