Every December, British music magazine NME compiles a list of what it considers the best singles or tracks of the year.
The companion list is NME album of the year The NME Single of the Year list is compiled by the music reviewers and independent journalists who work for the magazine and for NME.com.
Each picks his or her top 20 singles of the year and hands them in to the editor.
All of the points from the various top 20s are then gathered together and the overall favourites are worked out and ranked for publication in the official list.
There have been, to date, four artists who have won Album and Single of the Year in the same year: Joy Division in 1980, Klaxons in 2007, MGMT in 2008 and Lorde in 2017.
