BBC's 1Xtra has voted Ed Sheeran the "most important UK artist in the black and urban music scene".
The highest-placed black artist in the list was rapper Tinie Tempah in the third spot. At number two were Disclosure, who are two white brothers called Guy and Howard Lawrence, with white singer Sam Smith in fourth place.
When 1Xtra, which is labelled "the UK’s leading black music station", released the list, it was met with a fair bit of shock online.
And even Wiley, who was 16th (out of 20), was confused by the choice.
Artists were considered on variables such as sales statistics, quality of music and impact across the wider industry – it is not about the colour of someone's skin.
