(news.bbc.co.uk) - Singer Rihanna is dominating the UK pop music scene after reaching number one in both the singles and album charts. The 19-year-old's third album, Good Girl Gone Bad, entered the chart at number one, while her single Umbrella is on top for the fourth week running.
Scottish rock band Biffy Clyro's fourth album, Puzzle, entered the chart at number two, one place ahead of The Twang's Love It When I Feel Like This.
Sir Paul McCartney's Memory Almost Full was another new entry, at number five. The former Beatle promoted the album last week with a gig for just 1,000 people at London's Electric Ballroom venue.
