Have you ever wondered how much money was spent to get a song on the radio — and stuck in your head? NPR set out to discover just that, determining how much it costs to make a hit single, using Rihanna's song "Man Down" as a case study. Here's how the "eye-popping" bill breaks down, by the numbers:

Money spent on "song roll-out" after it's finished. "You want them to turn on the radio and hear Rihanna, turn on BET and see Rihanna, walk down the street and see a poster of Rihanna, look on Billboard, the iTunes chart, I want you to see Rihanna first," says Daniels. "All of that costs."

Rihanna's estimated net worth in 2011, according to VH1. Though "Man Down" hasn't sold well, Def Jam "makes up the shortfall by releasing other singles," says Chace. Rihanna only gets paid after the label recoups its investment on the album.
