VMP just paid attention in Econ 101:
"The first lesson of economics is scarcity: there is never enough of anything to fully satisfy all those who want it." -Thomas Sowell
Just because many of us think them not telling us the titles is bullshit, and their FOMO marketing is infuriating, why would they change? The Blue Note one sold out in under 3 hours. Why would VMP think this Motown Anthology won't sell out as well? If people don't sell this one out instantly, hopefully they'll adjust the way they market the next one. But if it sells out in a day, they have no impetus to change.
