Top of the Pops, 23rd April 2015

Somewhat unusually, there are only two top ten hits on the show this week, from Dr Kucho and new number 1 artiste Wiz Khalifa (only the video for him as he's out of the country). Never fear, though, as the lower reaches of the chart bring us a Mumfords medley, an exclusive, never-to-be-repeated Skrillex/Lethal Bizzle collaboration, the delightful Meghan Trainor, and Kodaline.

Why have the Killers re-entered the top 75? Dunno, but it's nice to watch a clip of them in their prime nonetheless.
