It's been a Britsy week. Five of our acts here are Brit Award winners or performers, including Bastille and Rudimental reprising their team-up from the ceremony itself (and even our presenter, Duffy, is a three-time former winner). Katy Perry even brings most of her set from the Brits show along with her. Non-Brit tracks include newies from Tegan and Sara and A Great Big World, plus a long-running mid-hit from Idina Menzel. Critics' Choice Sam Smith actually has four songs in the top 75, but this week is all about Money On My Mind.

Straight in at number 1PRESENTER: Duffy
A truckload of new tracks make up most of the show this week, although one of them was also performed last week in its rip-off version; Zedd and Hayley turn up in person today to knock it into a cocked hat. Further continuity comes from Katy B and the all-conquering Clean Bandit, back for a fourth time with another irrepressible rendition. Soul Queen Mary J Blige also pops in to add some regal glitter.

Fourth week at number 1PRESENTER: JB Gill
This week's big name is Katy Perry, here with Juicy J as Dark Horse gets a second wind and canters up to the top ten after seven weeks on the chart - a dark horse indeed. At the other end of the star spectrum is "DJ Stay The Night" with a pre-emptive cover of a not-yet-released song by Zedd; the collective of shadowy studio goons make the most of their week on the telly. Friends of the show OneRepublic give us a two-hit medley, and Clean Bandit are still at the top of the pile, grinning like the Cheshire cats they are.

Third week at number 1PRESENTER: Kimberley Walsh
Almost everything is new this week, though that's not to say there aren't some familiar faces. Will.i.am only brings one of his guest stars along this week, turning the track into an extended freestyle as he and French Montana try to top each other. Dappy is also in the building, on the back of his Celebrity Big Brother appearance, and Katy B does justice to her big dance ballad anthem. Holding fast at number 1 are Clean Bandit, who turn up this week with a full string section in tow.
