Top of the Pops, 29th January 2015

An unusually static chart means that TOTP has space for some long-runners as well as some gems from lower down the countdown than usual. Inevitably this means two corners of the Sheeran/Ezra/Smith triangle - there hasn't been a show without at least one of them since November - but it also means Ariana Grande and the Weeknd, who have been in the lower reaches for a few weeks, plus a couple of minutes of the Weeknd's solo offering - a bonanza of vaguely pervy RnB.

Meghan Trainor's second single is a storming success and the lady herself is in the country to perform it. We welcome back old favourites Sigma/Paloma and Vance Joy, and there's also a welcome suprise visit from Maroon 5. Ronson and Mars remain at the top, and after last week's studio appearance we make do with the video this time.
