Getting a song on the pop charts takes big money.
Def Jam started paying for Rihanna's recent single, "Man Down," more than a year ago. In March of 2010, the label held a writing camp in L.A. to create the songs for Rihanna's album, Loud.
At a writing camp, a record label hires the best music writers in the country and drops them into the nicest recording studios in town for about two weeks. It's a temporary version of the old music-industry hit factories, where writers and producers cranked out pop songs.
"It's like an all-star game," says Ray Daniels, who was at the writing camp for Rihanna.
