With the DIY revolution of bedroom laptop producers scoring huge hits, and with established multi-millionaire producers often sticking with the tools they started with back in the basement, it's harder than ever to really say how much a recording cost to make. In fact, the clout of a collaborator with name recognition remains probably the priciest component of most rap records—especially if Kanye is flying someone out to Hawaii or Paris just to work on a song instead of e-mailing their part in. But if something sounds shiny and opulent, if the beat is perfect for Rick Ross to lip sync to inside a giant mansion, then you can't go wrong describing the sound of the track as "expensive."
