Jive Records new golden boy Chris Brown has ended Kanye West?s 10-week run at the top of the US singles chart after spending four consecutive weeks at number two. Brown’s RUN IT! hit the top spot today, displacing West’s hit ?Gold Digger?. Even though West’s long run at number one is over, there are plenty more number one marathons being held on other singles charts in America. Kelly Rowland has been given a boost just two days after her last scheduled performance as a member of the R&B trio destiny?s Child. Her collaboration with Trina, Here We Go, is the Billboard chart’s greatest gainer this week, rising to number 19.
