Rick Ross says steady *Set In Stone* streams beat padded debuts after 50 Cent mocks his album sales and a Detroit crowd. Rick Ross is answering 50 Cent’s empty-seat joke by using Set In Stone sales to add fresh fuel to their endless feud. That was the lowest chart peak of Ross’ 12 solo albums, giving 50 Cent more ammo for their 17-year war. The pitch had a true Ross taste: music, liquor and money, served while 50 Cent checks his rival’s receipts without being asked. 50 Cent wrote Tuesday that Ross “CAN’T FAKE IT FOREVER,” keeping the door open for more jokes after both men finish counting this week’s numbers.
