Bruno Mars and Rihanna's singles are heading back into the UK top three after being performed on The X Factor, but they will not catch Olly Murs.
Sales of Mars' Atlantic-issued Locked Out Of Heaven are up 67% on the week so far to lift it 9-2 in midweeks, while Rihanna's Def Jam/Mercury track is up 36% to rise 10-3, according to the Official Charts Company.
Both tracks were performed on last Sunday's X Factor results show, the same platform on which the releases currently occupying positions 1, 4, 5 and 6 on the midweeks were also performed in previous weeks. Heading the race, Epic act Olly Murs featuring Flo Rida's Troublemaker is currently ahead by around 11,000 sales and should secure a second week at No 1 on Sunday. Labrinth's Syco single Beneath Your Beautiful featuring Emeli Sande holds at 4, while RCA act Alicia Keys' Girl On Fire remains at 5, while Robbie Williams' Island-issued Candy climbs back up 8-6, no doubt helped by his O2 arena shows in North Greenwhich.
Murs is also leading the artist albums midweeks as he looks to simultaneously head both main sales charts for the first time in his career. The newly-issued Epic album Right Place Right Time was nudging 90,000 sales by the end of business on Thursday and should safely accumulate a six-figure sales number by the end of the week, while Syco act One Direction's Take Me Hone holds at 2 and Rihanna's Def Jam/Mercury album Unapologetic drops 1-3. An expanded version of Michael Buble's Reprise/Warner Bros set Christmas lifts 5-4, while Girls Aloud's new Polydor best of Ten is new at 5.
There are also Top 10 new entries at this stage of the week from Neil Diamond and Jeff Wayne. Diamond's Columbia set The Very Best Of is at 9 and Wayne's The War Of The Worlds - New Generation from the same record company is at 10.
