Good news for Jase, Ri, Chez, Leona & The Beat

Since Wednesday, the midweeks have been a bit like Christopher Biggins's bowels after a chicken bhuna takeaway - there's been rather a lot of movement - so we'd better get right on with the Friday update.

Jason Derulo's replaced Flo Rascal at the summit, with Ellie Goulding still completing the top three.

It's champagne and China Whites for Rihanna, who's climbed another spot since Wednesday, but cocoa and an early night for Sugababes, who've slipped three.

Did someone say, "All publicity is good publicity"? Cheryl Cole's 'Parachute' is now just two places outside the top ten.

Also on the up are Leona, who's now in the top 15 with 'I Got You', and Alphabeat, who've climbed into the top 35 with 'Hole In My Heart'.

GaGa's fending off Glee and Florence at the top of the albums chart, while Marina's clinging assiduously to her position in the top five.

Right, time for the now traditional predictions - where do we think Boyzone, Daisy and Amy Macdonald are going to end up next week? And is the Ellie Goulding album heading for No.1? As ever, the box below is just begging for your best educated guesses.
