Gotye has landed an eighth week at the top of the U.S. pop charts with his break-up anthem "Somebody That I Used To Know." The Aussie star holds off Carly Rae Jepsen from the top of the charts for a second week. Her "Call Me Maybe" holds firm at number two. And Rihanna scores her 22nd top 10 in seven years with "Where Have You Been" - her second Hot 100 top 10 from her latest album "Talk That Talk." She spent 10 weeks at number one with "We Found Love."
