LONDON (Reuters) Bajan singer Rihanna equalled Madonna’s chart record of three consecutive number one albums this week, while X Factor talent show star Olly Murs scored his fourth number one single, the Official Charts Company said on Sunday. Rihanna’s “Unapologetic” went straight to the top of the singles chart, extending a run of album chart success with last year’s “Talk That Talk” and 2010’s “Loud”.
