Recently, a new term has ignited forums, fan groups, and auction sites: the . But what exactly is this release? Why has it caused such a seismic shift in the collector’s market? And is it worth the hype (and the price tag)?

However, some casual fans grumble that the "MegaPack" lacks her most famous mainstream drama, "Midnight Taxi," due to licensing conflicts with a competing streaming service. Furthermore, the vinyl record, while beautiful, is only two songs for a 40-minute runtime—a criticism of "style over substance."
