American rapper Wiz Khalifa's tribute to actor Paul Walker, "See You Again", kept the top spot in Britain's music charts for a second week, the Official Charts Company said on Sunday, saying it had also broken the country's all-time streaming record. A remix of OMI's 2012 reggae song "Cheerleader" held firm at number two, while "Hold My Hand", by Jess Glynne, remained at number three.??
